Genesis chapter 21 records which event?

• A. The Flood
• B. The Signing of the Covenant
• C. Birth of Isaac
• D. Theophany

Answer: (C)

The main idea here is the fulfillment of a promise through the birth of Isaac. Genesis 21 records the long-awaited birth of Abraham and Sarah’s son, Isaac, which marks the moment God keeps His covenant by bringing a child into their old age. Sarah’s initial doubt is turned to joy as she names him Isaac, meaning “he laughs,” recognizing how God has worked in a surprising, joyful way. The chapter also notes Isaac’s reception of the covenant sign through his circumcision on the eighth day, showing the ongoing line through which God’s blessings would continue. While the surrounding narrative includes events with Hagar and Ishmael and a later agreement with Abimelech at Beersheba, the focal event in this chapter is Isaac’s birth and the affirmation of God’s promise to Abraham and Sarah.
