'Sign' in the Bible

And he said, "Because I am with you, and this [will be] the sign for you that I myself have sent you: When you bring the people out from Egypt, you will serve God on this mountain."

"{And} if they do not believe you and they will not listen to the voice of the former sign, [then] they will believe the voice of the latter sign.

And I will put a distinction between my people and your people; this sign will be tomorrow.'"

And the blood will be a sign for you on the houses where you are, and I will see the blood, and I will pass over you, and there will not be a destructive plague among you when I strike the land of Egypt.

And it will be as a sign on your hand and as a memorial between your eyes so that the law of Yahweh will be in your mouth, that with a strong hand Yahweh brought you out from Egypt.

And it will be as a sign on your hand and as symbolic ornaments between your eyes that with strength of hand Yahweh brought us out from Egypt."

"And you, speak to the {Israelites}, saying, 'Surely you must keep my Sabbaths, because it [is] a sign between me and you throughout your generations, [in order] to know that I [am] Yahweh, who consecrates you.

It [is] a sign between me and the {Israelites} forever, because [in] six days Yahweh made the heavens and the earth, and on the seventh he ceased and recovered."
