God let the suffering old man go through with it up to the point where He knew there would be no retreat, and then forbade him to lay a hand upon the boy. To the wondering patriarch He now says in effect, “It’s all right, Abraham. I never intended that you should actually slay the lad. I only wanted to remove him from the temple of your heart that I might reign unchallenged there. I wanted to correct the perversion that existed in your love. Now you may have the boy, sound and well. Take him and go back to your tent. Now I know that thou fearest God, seeing that thou hast not withheld thy son, thine only son, from me.”

Then heaven opened and a voice was heard saying to him, “By myself have I sworn, saith the Lord, for because thou hast done this thing, and hast not withheld thy son, thine only son: that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.”
