Isaiah

Ask thee a sign of the Lord thy God; ask it either in the depth, or in the height above.

And this shall be a sign unto thee, Ye shall eat this year such as groweth of itself; and the second year that which springeth of the same: and in the third year sow ye, and reap, and plant vineyards, and eat the fruit thereof.

Behold, I will put a fleece of wool in the floor; and if the dew be on the fleece only, and it be dry upon all the earth beside, then shall I know that thou wilt save Israel by mine hand, as thou hast said.

And Gideon said unto God, Let not thine anger be hot against me, and I will speak but this once: let me prove, I pray thee, but this once with the fleece; let it now be dry only upon the fleece, and upon all the ground let there be dew.

And he said unto him, If now I have found grace in thy sight, then shew me a sign that thou talkest with me.
