In the beginning of your months The third stated sacrifice was monthly, to be offered on the first day of every month. This sacrifice to God is thought to have been ordained in opposition to the idolatry of the Gentiles, who were wont to worship the new moon with great rejoicings. Besides the celebration of the new moon by sacrifices, and sound of trumpet, (Numbers 10:10,) the Jews were wont upon those days to assemble for receiving instruction from their prophets, (2 Kings 4:23,) and to feast together, 1 Samuel 20:5; 1 Samuel 20:18. And it was customary on those days to shut up their shops, and abstain from ordinary and servile labour, as is hinted Amos 8:5.
