'New Moon' in the Bible

Behold, I am about to build a house for the name of Jehovah my God, to dedicate it to him, and to burn before him incense of sweet spices, and for the continual showbread, and for the burnt-offerings morning and evening, on the sabbaths, and on the new moons, and on the set feasts of Jehovah our God. This is an ordinance for ever to Israel.

even as the duty of every day required, offering according to the commandment of Moses, on the sabbaths, and on the new moons, and on the set feasts, three times in the year, even in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles.

He appointed also the king's portion of his substance for the burnt-offerings, to wit , for the morning and evening burnt-offerings, and the burnt-offerings for the sabbaths, and for the new moons, and for the set feasts, as it is written in the law of Jehovah.
