'New Moons' in the Bible

Behold, I am about to build a house for the name of Yahweh my God, to dedicate it to him, and to burn before him incense of sweet spices, and for the continual show bread, and for the burnt offerings morning and evening, on the Sabbaths, and on the new moons, and on the set feasts of Yahweh our God. This is [an ordinance] forever 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 tents.

[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 Yahweh.
