'Signs' in the Bible

I thought it good to shew the signs and wonders that the high God hath wrought toward me.

How great are his signs! and how mighty are his wonders! his kingdom is an everlasting kingdom, and his dominion is from generation to generation.

He delivereth and rescueth, and he worketh signs and wonders in heaven and in earth, who hath delivered Daniel from the power of the lions.
