The Feast of the New Moon: Celebrated with Blowing of Trumpets

And on your joyous occasions, your appointed feasts, and the beginning of each month, you are to blow the trumpets over your burnt offerings and peace offerings to serve as a reminder for you before your God. I am the LORD your God.”

Sound the ram’s horn at the New Moon, and at the full moon on the day of our Feast.

For this is a statute for Israel, an ordinance of the God of Jacob.
