'Sign' in the Bible

He gave a sign that day. He said, “This is the sign that the Lord has spoken: ‘The altar will now be ripped apart, and the ashes that are on it will be poured out.’”

The altar was ripped apart, and the ashes poured from the altar, according to the sign that the man of God had given by the word of the Lord.

Now the men were looking for a sign of hope, so they quickly picked up on this and responded, “Yes, it is your brother Ben-hadad.”Then he said, “Go and bring him.”So Ben-hadad came out to him, and Ahab had him come up into the chariot.
