'Signs' in the Bible

But after they had taken it away, the hand of the Lord was stretched out against the town for its destruction: and the signs of disease came out on all the men of the town, small and great.

And when these signs come to you, see that you take the chance which is offered you; for God is with you.

And it came about, that when he went away from Samuel, God gave him a changed heart: and all those signs took place that day.
