Shabbat is a SIGN; is a COVENANT between Y-H-V-H and us.

Eze 20:12

Eze 20:19
I am the Y-H-V-H your God; walk in My statutes, and keep My judgments, and do them;
Eze 20:20
And hallow My Shabbats; and they shall be a SIGN between Me and you, that ye may know that I am the LORD your God.

Mat 5:18

Mar 1:21

Act 17:2
