'Signs' in the Bible

This is what the Lord says, the Creator of the signs: "Question me about my children, or give me orders about the work of my hands.

"I will put up signs among them, and from them I will send survivors to the nations to Tarshish, Libya, and Lydia, (who draw the bow), to Tubal and Greece, to the far off coastlands that have not heard of my fame or seen my glory. Then they will proclaim my glory among the nations.
