And it shall come to pass, if they will not believe you, neither hearken to the voice of the first sign, that they will believe the voice of the latter sign.

And I will put a division between my people and your people: tomorrow shall this sign be.

And it shall be for a sign unto you upon your hand, and for a memorial before your eyes, that the LORD's law may be in your mouth: for with a strong hand has the LORD brought you out of Egypt.

And it shall be for a sign upon your hand, and for frontlets between your eyes: for by strength of hand the LORD brought us forth out of Egypt.

Speak also unto the children of Israel, saying, Verily my sabbaths you shall keep: for it is a sign between me and you throughout your generations; that you may know that I am the LORD that does sanctify you.

It is a sign between me and the children of Israel forever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
