'Token' in the Bible

For just as Jonah became a sign to the men of Nineveh, so the Son of Man will be a token to the present generation.

Symeon blessed them and said to Mary the mother, "This child is appointed for the falling and the uprising of many in Israel and for a token to be spoken against;

"Rabbi, when will this be?" they asked Him, "and what will be the token given when these things are about to take place?"

And this is the token for you: you will find a babe wrapped in swaddling clothes and lying in a manger."
