The Astronomy of the Bible / An Elementary Commentary on the Astronomical References of Holy Scripture

by E. Walter Maunder

Modern civilization has almost shut us off from the heavens, at least in our great towns and cities. These offer many conveniences, but they remove us from not a few of the beauties which nature has to offer. And so it comes that, taking the population as a whole, there is perhaps less practically known of astronomy in England to-day than there was under the Plantagenets. A very few are astronomers, professional and amateur, and know immeasurably more than our forefathers did of the science. Then there is a large, more or less cultured, public that know something of the science at secondhand through books. But the great majority know nothing of the heavenly bodies except of the sun; they need to "look in the almanack" to "find out moonshine." But to simpler peoples the difference between the "light half" of the month, from the first quarter to the last quarter through the full of the moon, and the "dark half," from the last quarter to the first quarter, through new, is very great. Indian astronomers so divide the month to this day.

In one passage of Holy Scripture, the description which Isaiah gives of the "City of the Lord, the Zion of the Holy One of Israel," there is a reference to the dark part of the month.

"Thy sun shall no more go down; neither shall thy moon (literally "month") withdraw itself: for the Lord shall be thine everlasting light, and the days of thy mourning shall be ended."

The parallelism expressed in the verse lies between the darkness of night whilst the sun is below the horizon, and the special darkness of those nights when the moon, being near conjunction with the sun, is absent from the sky during the greater part or whole of the night hours, and has but a small portion of her disc illuminated. Just as half the day is dark because the sun has withdrawn itself, so half the nights of the month are dark because the moon has withdrawn itself.

The Hebrew month was a natural one, determined by actual observation of the new moon. They used three words in their references to the moon, the first of which, chodesh, derived from a root meaning "to be new," indicates the fact that the new moon, as actually observed, governed their calendar. The word therefore signifies the new moon—the day of the new moon: and thus a month; that is, a lunar month beginning at the new moon. This is the Hebrew word used in the Deluge story in the seventh chapter of Genesis; and in all references to feasts depending on a day in the month. As when the Lord spake to Moses, saying, "Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with your trumpets over your burnt offerings, and over the sacrifices of your peace offerings." And again in the Psalm of Asaph to the chief musician upon Gittith: "Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day." This is the word also that Isaiah uses in describing the bravery of the daughters of Zion, "the tinkling ornaments about their feet, and their cauls, and their round tires like the moon, the chains, and the bracelets." "The round tires" were not discs, like the full moon, but were round like the crescent.

Generally speaking, chodesh is employed where either reference is made to the shape or newness of the crescent moon, or where "month" is used in any precise way. This is the word for "month" employed throughout by the prophet Ezekiel, who is so precise in the dating of his prophecies.

When the moon is mentioned as the lesser light of heaven, without particular reference to its form, or when a month is mentioned as a somewhat indefinite period of time, then the Hebrew word yarēach, is used. Here the word has the root meaning of "paleness"; it is the "silver moon."

Yarēach is the word always used where the moon is classed among the heavenly bodies; as when Joseph dreamed of the sun, the moon, and the eleven constellations; or in Jer. viii. 2, where the Lord says that they shall bring out the bones of the kings, princes, priests, prophets, and inhabitants of Jerusalem, "and they shall spread them before the sun, and the moon, and all the host of heaven, whom they have loved, and whom they have served, and after whom they have walked, and whom they have sought, and whom they have worshipped."

The same word is used for the moon in its character of "making ordinances." Thus we have it several times in the Psalms: "He (the Lord) appointed the moon for seasons." "His seed shall endure for ever, and his throne as the sun before Me. It shall be established for ever as the moon, and as a faithful witness in heaven." And again: "The moon and stars rule by night;" whilst Jeremiah says, "Thus saith the Lord, Which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night."

In all passages where reference seems to be made to the darkening or withdrawing of the moon's light (Eccl. xii. 2; Isa. xiii. 10; Ezek. xxxii. 7; Joel ii. 10, 31, and iii. 15; and Hab. iii. 11) the word yarēach is employed. A slight variant of the same word indicates the month when viewed as a period of time not quite defined, and not in the strict sense of a lunar month. This is the term used in Exod. ii. 2, for the three months that the mother of Moses hid him when she saw that he was a goodly child; by Moses, in his prophecy for Joseph, of "Blessed of the Lord be his land . . . for the precious fruits brought forth by the sun, and for the precious things put forth by the months." Such a "full month of days" did Shallum the son of Jabesh reign in Samaria in the nine and thirtieth year of Uzziah, king of Judah. Such also were the twelve months of warning given to Nebuchadnezzar, king of Babylon, before his madness fell upon him. The same word is once used for a true lunar month, viz. in Ezra vi. 15, when the building of the "house was finished on the third day of the month Adar, which was in the sixth year of the reign of Darius the king." In all other references to the months derived from the Babylonians, such as the "month Chisleu" in Neh. i. 1, the term chodesh is used, since these, like the Hebrew months, were defined by the observation of the new moon; but for the Tyrian months, Zif, Bul, Ethanim, we find the term yerach in three out of the four instances.
