'New moon' in the Bible

If you keep the Sabbath with care, not doing your business on my holy day; and if the Sabbath seems to you a delight, and the new moon of the Lord a thing to be honoured; and if you give respect to him by not doing your business, or going after your pleasure, or saying unholy words;

And it will be, that from new moon to new moon, and from Sabbath to Sabbath, all flesh will come to give worship before me, says the Lord.
