'New Moons' in the Bible

The Regent Prince is to provide the burnt offerings, grain offerings, and drink offerings at the festivals, on the New Moons and Sabbaths, and at all of the prescribed festivals of the house of Israel. He is to provide the grain offerings, burnt offerings, and peace offerings in order to make atonement for the house of Israel."

The people who live in the land are to worship at the doorway of the gate on the Sabbaths and New Moons in the LORD's presence.'"
