Thus the heavens and the earth were finished,
and all the host of them.
And on the seventh day God ended his work which he had made;
and he rested on the seventh day from all his work which he had made.
And God blessed the seventh day, and sanctified it:
because that in it he had rested from all his work which God created and made.

Come do all flesh to bow themselves before Me, Said Jehovah.
Isaiah 66:23 YLT

Come do all flesh to bow themselves before Me, Said Jehovah.
