And Isaiah said to him: "This will be the sign from the Lord, that the Lord will do the word that he has spoken: Do you wish that the shadow may ascend ten lines, or that it may turn back for the same number of degrees?"
For this reason, the Lord himself will grant to you a sign. Behold, a virgin will conceive, and she will give birth to a son, and his name will be called Immanuel.
And the Lord looked down upon him, and he said: "Go forth with this, your strength, and you shall free Israel from the hand of Midian. Know that I have sent you."
I will set this wool fleece on the threshing floor. If there will be dew only on the fleece, and all the ground is dry, I will know that by my hand, as you have said, you will free Israel."
