'New Moon' in the Bible

Bring no more vain offerings; incense is an abomination unto me; the new moons and sabbaths, the calling of assemblies, I cannot endure; it is iniquity, even the solemn meeting.

Your new moons and your appointed feasts my soul hates: they are a trouble unto me; I am weary of bearing them.

And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, says the LORD.
