Less clearly in the fifth, the fifty-ninth, and the eighty-eighth psalms, the morning prayer appears to be connected with the morning sacrifice:
"O Lord, in the morning shalt Thou hear my voice;
In the morning will I order my prayer unto Thee, and will keep watch" (Psalm v. 3).
The pious Hebrew might naturally choose the morning and the evening as his times of special approach to the throne of Divine grace, as every believer still feels it his duty and privilege to begin and close the day with prayer. The appropriateness of dawn and sunset might determine both the hour of sacrifice and the hour of private worship. Yet the ordinance of the daily oblations set an example to those who would otherwise have been careless in expressing gratitude. And earnestly religious persons learned to find more frequent opportunities. Daniel in Babylon is seen at the window open towards Jerusalem, kneeling upon his knees three times a day, praying and giving thanks to God. The author of Psalm cxix. says:
"Seven times a day do I praise Thee,
Because of Thy righteous judgments."
The grateful remembrance of God and confession of His right to the whole of life were thus made a rule with which no other engagements were allowed to interfere. It is by facts like these the power of religion over the Hebrews in their best time is explained.
We pass now to the Sabbath and the sacrifices by which it was distinguished. Here the number seven which recurs so frequently in the statutes of the sacred year appears for the first time. Connection has been found between the ordinances of Israel and of Chaldea in the observance of the seventh day as well as at many other points. According to Mr. Sayce, the origin of the Sabbath went back to pre-Semitic days, and the very name was of Babylonian origin. "In the cuneiform tablets the sabbatu is described as a 'day of rest for the soul.'... The Sabbath was also known, at all events in Accadian times, as a dies nefastus, a day on which certain work was forbidden to be done; and an old list of Babylonian festivals and fast-days tells us that on the seventh, fourteenth, nineteenth, twenty-first, and twenty-eighth days of each month the Sabbath rest had to be observed. The king himself, it is stated, 'must not eat flesh that has been cooked over the coals or in the smoke, he must not change the garments of his body, white robes he must not wear, sacrifices he may not offer, in a chariot he must not ride.'" The soothsayer was forbidden on that day "to mutter in a secret place." In this observance of a seventh day of rest, specially sacred, for the good of the soul, ancient Accadians and Babylonians prepared the way for the Sabbath of the Mosaic law.
But while the days of the Chaldean week were devoted each to a separate divinity, and the seventh day had its meaning in relation to polytheism, the whole of time, every day alike, and the Sabbaths with greater strictness than the others, were, in Israel's law, consecrated to Jehovah. This difference also deserves to be noticed, that, while the Chaldean seventh days were counted from each new moon, in the Hebrew year there was no such astronomical date for reckoning them. Throughout the year, as with us, each seventh day was a day of rest. While we find traces of old religious custom and observance that mingled with those of Judaism and cannot but recognise the highly humane, almost spiritual character those old institutions often had, the superiority of the religion of the One Living and True God clearly proves itself to us. Moses, and those who followed him, felt no need of rejecting an idea they met with in the ancient beliefs of Chaldea, for they had the Divine light and wisdom by which the earthly and evil could be separated from the kernel of good. And may we not say that it was well to maintain the continuity of observance so far as thoughts and customs of the far past could be woven into the worship of Jehovah's flock? Neither was Israel nor is any people to pretend to entire separation from the past. No act of choice or process of development can effect it. Nor would the severance, if it were made, be for the good of men. Beyond the errors and absurdities of human belief, beyond the perversions of truth due to sin, there lie historical and constitutional origins. The Sabbaths, the sacrifices, and the prayers of ancient Chaldea had their source in demands of God and needs of the human soul, which not only entered into Judaism, but survive still, proving themselves inseparable from our thought and life.
The special oblations to be presented on the Sabbath were added to those of the other days of the week. Two lambs of the first year in the morning and two in the evening were to be offered with their appropriate meal and drink offerings. It may be noted that in Ezekiel where the Sabbath ordinances are detailed the sacrifices are more numerous. After declaring that the eastern gate of the inner court of the temple, which is to be shut on the six working days, shall be opened on the Sabbath and in the day of the new moon, the prophet goes on to say that the prince, as representing the people, shall offer unto the Lord in the Sabbath day six lambs without blemish and a ram without blemish. In the legislation of Numbers, however, the higher consecration of the Sabbath as compared with the other days of the week did not require so great a difference as Ezekiel saw it needful to make. And, indeed, the law of Sabbath observance assumes in Ezekiel an importance on various grounds which passes beyond the high distinction given it in the Pentateuch. Again and again in chapter xx. the prophet declares that one of the great sins of which the Israelites were guilty in the wilderness was that of polluting the Sabbath which God had given to be a sign between Himself and them. The keeping holy of the seventh day had become one of the chief safeguards of religion, and for this reason Ezekiel was moved to prescribe additional sacrifices for that day.
We find as we go on that the week of seven days, ended by the recurring day of rest, is an element in the regulations for all the great feasts. Unleavened bread was to be eaten for seven days. Seven weeks were then to be counted to the day of the firstfruits and the feast of weeks. The feast of tabernacles, again, ran for seven days and ended on the eighth with a solemn assembly. The whole ritual was in this way made to emphasise the division of time based on the fourth commandment.
