Genesis 20 gives the account of Abraham's encounter with the king of Gerar, Abimelech. Here again, Abraham did not have faith in God to protect himself and his wife , so he told yet another king that Sarah was his sister. But, God in His mercy did not allow the king to take Sarah and God came to him in a dream and told him the truth. Upon learning about Abraham's lie, Abimelech was surprisingly gracious to Abraham and gave him gifts of sheep and cattle and offered to let him live anywhere in his land. Abraham prayed to God for healing for Abimelech and his wife and family and God restored their fertility.
