Sarai (Sarah) was the wife of Abram (Genesis 16:1). They both had the same father but different mothers (Genesis 20:12). This was accepted at that time. Abram and his wife lived originally in Ur, in the land of the Chaldees and worshiped the living God (Genesis 12:1–4; 15:6). The Lord commanded Abram to leave Ur to a land that He would should him.
As they traveled they faced a famine, so they went to Egypt (Genesis 12:10). Abram was afraid that the Egyptians would kill him and take his wife because she was very beautiful. So, he asked her to say that she was his sister (a half-truth). Pharaoh found about Abraham’s wife and took her to his house. But God intervened and plagued Pharaoh’s house and he returned Abram’s wife (Genesis 12).
Abram and his wife reached the land that God led them to. And there, God promised Abram a son and that his descendants would be as the stars of heaven (Genesis 15) and inherit Canaan. But Sarai was barren. When ten years passed and still there was no child, she asked Abram to have a child with her servant Hagar (Genesis 16:2,3). Abraham did as she suggested and Hagar conceived. When Hagar saw that she had conceived, her mistress became despised in her eyes. So, Sarai dealt harshly with her, and Hagar fled from her presence (verses 4-8).
Then, the Angel of the Lord, who found Hagar by a spring of water in the wilderness, said to her to go back to her mistress and that God will bless her child (Genesis 16:11-12). So, Hagar went back to Abram and Sarai and gave birth to Ishmael. Abram was eighty-six years old when Hagar bore Ishmael (Genesis 16:15). When Abram was ninety-nine years old, the Lord appeared to him and changed his name to Abraham and Sarai to Sarah. And the Lord reaffirmed His promise to Abraham that He will make him the father of many nations through Sarah not Hagar (Genesis 17:1-19) according to God’s original covenant (Genesis 15).
God fulfilled His promise to Abraham and Sarah and gave them Isaac (Genesis 21:1). When Isaac was weaned, Abraham held a feast. But Ishmael, Hagar’s son, was mocking Isaac. So, Sarah told Abraham that He needed to send Hagar and Ishmael away. Abraham didn’t want that, but God told him to do that. Abraham sent Hagar and Ishmael away (Genesis 21:8–21) remembering God’s promise of blessing Ishmael and making him a great nation (Genesis 17:20).
Sarah believed in the living God and in His unchanging Word. Even though she was 90 and Abraham was 100, she trusted that the Lord will fulfill His promise by giving them a son when she passed the age of fertility. She died at the age of 127 (Genesis 23:1). During her life she respected Abraham and submitted to his headship in the home (Genesis 18:12). The apostle Peter points to her as the matriarch of all godly wives (1 Peter 3:5–6).
