What the Bible Says About Worshipping the Moon
A large proportion of the people of Israel, long after their settlement in Palestine, maintained the habits of their forefathers, and led the shepherd's life. To them, therefore, the full of the moon must have been of special importance; yet there is no single reference in Scripture to this phase as such; nor indeed to any change of the moon's apparent figure. In two cases in our Revised Version we do indeed find the expression "at the full moon," but if we compare these passages with the Authorized Version, we find them there rendered "in the time appointed," or "at the day appointed." This latter appears to be the literal meaning, though there can be no question, as is seen by a comparison with the Syriac, that the period of the full moon is referred to. No doubt it was because travelling was so much more safe and easy than in the moonless nights, that the two great spring and autumn festivals of the Jews were held at the full moon. Indeed, the latter feast, when the Israelites "camped out" for a week "in booths," was held at the time of the "harvest moon." The phenomenon of the "harvest moon" may be briefly explained as follows. At the autumnal equinox, when the sun is crossing from the north side of the equator to the south, the full moon is crossing from the south side of the equator to the north. It is thus higher in the sky, when it souths, on each succeeding night, and is therefore up for a greater length of time. This counterbalances to a considerable extent its movement eastward amongst the stars, so that, for several nights in succession, it rises almost at sundown. These nights of the Feast of Tabernacles, when all Israel was rejoicing over the ingathered fruits, each family in its tent or arbour of green boughs, were therefore the fullest of moonlight in the year.

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 moon's influence in raising the tides is naturally not mentioned. The Hebrews were not a seafaring race, nor are the tides on the coast of Palestine pronounced enough to draw much attention. One influence is ascribed to the moon; an influence still obscure, or even disputed. For the promise that—
"The sun shall not smite thee by day,Nor the moon by night,"
quite obvious in its application to the sun, with the moon seems to refer to its supposed influence on certain diseases and in causing "moon-blindness."
The chief function of the moon, as indicated in Scripture, is to regulate the calendar, and mark out the times for the days of solemnity. In the words of the 104th Psalm:—
"He (God) appointed the moon for seasons:The sun knoweth his going down.Thou makest darkness, and it is night;Wherein all the beasts of the forest do creep forth.The young lions roar after their prey,And seek their meat from God.The sun ariseth, they get them away,And lay them down in their dens.Man goeth forth unto his workAnd to his labor until the evening.O Lord, how manifold are Thy works!In wisdom hast Thou made them all:The earth is full of Thy riches."
