This psalm is closely related to Psalms cv.-cvii.

Like them, it treats the history of Israel, and especially the Exodus and wilderness wanderings, for purposes of edification, rebuke, and encouragement. The past is held up as a mirror to the present generation. It has been one long succession of miracles of mercy met by equally continuous ingratitude, which has ever been punished by national calamities. The psalm departs singularly from chronological order. It arranges its contents in two principal masses, each introduced by the same formula (vv. 12, 43) referring to "wonders in Egypt and the field of Zoan." But the first mass has nothing to do with Egypt, but begins with the passage of the Red Sea, and is wholly occupied with the wilderness. The second group of wonders begins in ver. 44 with the plagues of Egypt, touches lightly on the wilderness history, and then passes to the early history of Israel when settled in the land, and finishes with the establishment of David on the throne. It is difficult to account for this singular bouleversement of the history. But the conjecture may be hazarded that its reason lies in the better illustration of continual interlacing of mercy and unthankfulness afforded by the events in the wilderness, than by the plagues of Egypt. That interlacing is the main point on which the psalmist wishes to lay stress, and therefore he begins with the most striking example of it. The use of the formula in ver. 12 looks as if his original intention had been to follow the order of time. Another peculiarity is the prominence given to Ephraim, both in ver. 9 as a type of faithlessness, and in ver. 67 as rejected in favour of Judah. These references naturally point to the date of the psalm as being subsequent to the separation of the kingdoms; but whether it is meant as rebuke to the northern kingdom, or as warning to Judah from the fate of Ephraim, is not clear. Nor are there materials for closer determination of date. The tone of the closing reference to David implies that his accession belongs to somewhat remote times.

There are no regular strophes, but a tendency to run into paragraphs of four verses, with occasional irregularities.

Vv. 1-4 declare the singer's didactic purpose. He deeply feels the solidarity of the nation through all generations—how fathers and children are knit by mystic ties, and by possession of an eternal treasure, the mighty deeds of God, of which they are bound to pass on the record from age to age. The history of ancient days is "a parable" and a "riddle" or "dark saying," as containing examples of great principles, and lessons which need reflection to discern and draw out. From that point of view, the psalmist will sum up the past. He is not a chronicler, but a religious teacher. His purpose is edification, rebuke, encouragement, the deepening of godly fear and obedience. In a word, he means to give the spirit of the nation's history.

Vv. 5-8 base this purpose on God's declared will that the knowledge of His deeds for Israel might be handed down from fathers to sons. The obligations of parents for the religious training of their children, the true bond of family unity, the ancient order of things when oral tradition was the principal means of preserving national history, the peculiarity of this nation's annals, as celebrating no heroes and recording only the deeds of God by men, the contrast between the changing bearers of the story and the undying deeds which they had to tell, are all expressed in these verses, so pathetic in their gaze upon the linked series of short-lived men, so stern in their final declaration that Divine commandment and mercy had been in vain, and that, instead of a tradition of goodness, there had been a transmission of stubbornness and departure from God, repeating itself with tragic uniformity. The devout poet, who knows what God meant family life to be and to do, sadly recognises the grim contrast presented by its reality. But yet he will make one more attempt to break the flow of evil from father to son. Perhaps his contemporaries will listen and shake themselves clear of this entail of disobedience.

The reference to Ephraim in vv. 9-11 is not to be taken as alluding to any cowardly retreat from actual battle. Ver. 9 seems to be a purely figurative way of expressing what is put without a metaphor in the two following verses. Ephraim's revolt from God's covenant was like the conduct of soldiers, well armed and refusing to charge the foe. The better their weapons, the greater the cowardice and ignominy of the recreants. So the faithlessness of Ephraim was made darker in criminality by its knowledge of God and experience of His mercy. These should have knit the tribe to Him. A general truth of wide application is implied—that the measure of capacity is the measure of obligation. Guilt increases with endowment, if the latter is misused. A poor soldier, with no weapon but a sling or a stick, might sooner be excused for flight than a fully armed archer. The mention of Ephraim as prominent in faithlessness may be an allusion to the separation of the kingdoms. That allusion has been denied on the ground that it is the wilderness history which is here before the psalmist's mind. But the historical retrospect does not begin till ver. 12, and this introduction may well deal with an event later than those detailed in the following verses. Whether the revolt of the Ten Tribes is here in view or not, the psalmist sees that the wayward and powerful tribe of Ephraim had been a centre of religious disaffection, and there is no reason why his view should not be believed, or should be supposed to be due to mere prejudiced hostility.

The historical details begin with ver. 12, but, as has been noticed above, the psalmist seems to change his intention of first narrating the wonders in Egypt, and passes on to dilate on the wilderness history. "The field of Zoan" is the territory of the famous Egyptian city of Tzan, and seems equivalent to the Land of Goshen. The wonders enumerated are the familiar ones of the passage of the Red Sea, the guidance by the pillar of cloud and fire, and the miraculous supply of water from the rock. In vv. 15, 16, the poet brings together the two instances of such supply, which were separated from each other by the forty years of wandering, the first having occurred at Horeb in the first year, and the second at Kadesh in the last year. The two words "rocks," in ver. 15, and "cliff," in ver. 16, are taken from the two narratives of these miracles, in Exod. xvii. and Numb. xx.

The group of four verses (13-16) sets forth God's mighty deeds; the next quartet of verses (17-20) tells of Israel's requital. It is significant of the thoughts which filled the singer's heart, that he begins the latter group with declaring that, notwithstanding such tokens of God's care, the people "went on to sin yet more," though he had specified no previous acts of sin. He combines widely separated instances of their murmurings, as he had combined distant instances of God's miraculous supply of water. The complaints which preceded the fall of the manna and the first supply of quails (Exod. xvi.), and those which led to the second giving of these (Numb. xi.) are thrown together, as one in kind. The speech put into the mouths of the murmurers in vv. 19, 20, is a poetic casting into bitter, blasphemous words of the half-conscious thoughts of the faithless, sensuous crowd. They are represented as almost upbraiding God with His miracle, as quite unmoved to trust by it, and as thinking that it has exhausted His power. When they were half dead with thirst, they thought much of the water, but now they depreciate that past wonder as a comparatively small thing. So, to the churlish heart, which cherishes eager desires after some unattained earthly good, past blessings diminish as they recede, and leave neither thankfulness nor trust. There is a dash of intense bitterness and ironical making light of their relation to God in their question, "Can He provide flesh for His people?" Much good that name has done us, starving here! The root of all this blasphemous talk was sensuous desire; and because the people yielded to it, they "tempted God"—that is, they "unbelievingly and defiantly demanded, instead of trustfully waiting and praying" (Delitzsch). To ask food for their desires was sin; to ask it for their need would have been faith.

In ver. 21 the allusion is to the "fire of the Lord," which, according to Numb. xi. 3, burnt in the camp, just before the second giving of quails. It comes in here out of chronological order, for the sending of manna follows it; but the psalmist's didactic purpose renders him indifferent to chronology. The manna is called "corn of heaven" and "bread of the Mighty Ones"—i.e., angels, as the LXX. renders the word. Both designations point to its heavenly origin, without its being necessary to suppose that the poet thought of angels as really eating it. The description of the fall of the quails (vv. 26-29) is touched with imaginative beauty. The word rendered above "made to go forth" is originally applied to the breaking up an encampment, and that rendered "guided" to a shepherd's leading of his flock. Both words are found in the Pentateuch, the former in reference to the wind that brought the quails (Numb. xi. 31), the latter in reference to that which brought the plague of locusts (Exod. x. 13). So the winds are conceived of as God's servants, issuing from their tents at His command, and guided by Him as a shepherd leads his sheep. "He let it fall in the midst of their camp" graphically describes the dropping down of the wearied, storm-beaten birds.
