'New Moon' in the Bible

Bring no more vain oblations! Incense is an abomination unto me, new moon and sabbath, the calling of convocations wickedness and the solemn meeting I cannot bear.

Your new moons and your set feasts my soul hateth: they are a burden to me; I am wearied of bearing them.

Thou art wearied in the multitude of thy counsels. Let now the interpreters of the heavens, the observers of the stars, who predict according to the new moons what shall come upon thee, stand up, and save thee.

And it shall come to pass from new moon to new moon, and from sabbath to sabbath, all flesh shall come to worship before me, saith Jehovah.
