'New moon' in the Bible

“Bring your worthless offerings no longer,Incense is an abomination to Me.New moon and sabbath, the calling of assemblies—I cannot endure iniquity and the solemn assembly.

“I hate your new moon festivals and your appointed feasts,They have become a burden to Me;I am weary of bearing them.

“And it shall be from new moon to new moonAnd from sabbath to sabbath,All mankind will come to bow down before Me,” says the Lord.
