TSK · Isaiah 38:7

I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.

behold, I will put a fleece of wool on the threshing-floor; if there be dew on the fleece only, and it be dry upon all the ground, then shall I know that thou wilt save Israel by my hand, as thou hast spoken.

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

And this shall be the sign unto thee: ye shall eat this year that which groweth of itself, and in 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.
