TSK · Isaiah 38:7

I set my rainbow in the cloud, and it will be for a sign 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 on all the ground, then shall I know that you will save Israel by my hand, as you have spoken."

"Ask a sign of Yahweh your God; ask it either in the depth, or in the height above."

This shall be the sign to you. You will eat this year that which grows of itself, and in the second year that which springs from the same; and in the third year sow and reap and plant vineyards, and eat their fruit.
