When Abraham and Sarah were given a child, they were very happy and named him Isaac.
But, one day, God decided to test Abraham's faith and Abraham followed.
Take your son Isaac, your only one, whom you love, and go to the land of Moriah. There, you shall offer him as a holocaust on a height that I will point out to you.
With Isaac and two other servants, they journeyed following the path God gave them. After three days, they arrived.
Yaweh-yireh (The Lord will Provide)
I swear by myself, declares the Lord, that because you acted as you did in not withholding from me your beloved son, I will bless you abundantly and make your descendants as countless as the stars of the sky and the sands of the seashore.
Do not lay your hand on the boy. Do not do the least thing to him. I know now how devoted you are to God, since you did not withhold from me your own beloved son.
