# Two heads identified as those of Abraham and his son Isaac

Abraham is often referred to as the father of believers. A patriarch, Abraham becomes a father to his wife Sarah at a very old age.

In the Bible, Abraham agrees to sacrifice his only son. God stops him and substitutes his son with a ram, promising Abraham that he will be the father of an innumerable people.
