Genesis 9:18-19,17:1-8, 21:1-7; Matthew 1:1-16
Many years went by and the descendants of Noah became many tribes. Abraham was one of these descendants. He was a man who also loved and obeyed God. God promised Abraham that his descendants would become a great people. Abraham and his wife Sarah did not have any children at that time, but they still believed God's promise. When they were very old, they had a son whom they called Isaac, who was born by a miracle. God promised to do something very special through Isaac and his descendants. Abraham had children by other women. One of those children was named Ishmael. He became the father of the Arab nations.
