'New Moon' in the Bible

And in the day of your gladness, and in your set feasts, and in your new moons, ye shall blow with the trumpets over your burnt-offerings and over your sacrifices of peace-offering; and they shall be to you for a memorial before your God: I am Jehovah your God.

besides the burnt-offering of the new moon, and the meal-offering thereof, and the continual burnt-offering and the meal-offering thereof, and their drink-offerings, according unto their ordinance, for a sweet savor, an offering made by fire unto Jehovah.
