Question 1

What exactly does God tell Abraham to do regarding Sarai’s name in verse 15?

Accepted Answer

Verse 15 contains a direct instruction from God to Abraham about what Abraham is to call his wife. Abraham is told to stop using the name “Sarai” and to use “Sarah” instead. The wording makes the change sound decisive and ongoing (“you shall not call… but her name will be…”). The text does not present this as Abraham’s choice or a private nickname; it is framed as God’s determination of her public identity within the covenant story.

Question 2

In verses 15–16, who is the focus of God’s promise, and how can you tell?

Accepted Answer

Although God speaks to Abraham, the promise repeatedly centers on Sarah. God changes her name, says “I will bless her” (twice), and states “I will give you a son by her.” Those phrases place Sarah at the center of what God is doing. Abraham remains involved (“I will give you”), but the passage highlights that Sarah is not merely connected to Abraham’s blessing; she herself is named and blessed as part of the promised outcome.

Question 3

What are the distinct promises made in verse 16, and how are they related?

Accepted Answer

Verse 16 stacks several promises: God will bless Sarah; God will give Abraham a son by Sarah; God will bless her again (repeating for emphasis); Sarah will become a mother of nations; and kings of peoples will come from her. These promises build outward: personal blessing → a specific child through Sarah → a broad future line of descendants with political significance. The logic suggests the child is a starting point for a much larger family line.

Question 4

What does the repeated statement “I will bless her” contribute to the meaning of the passage?

Accepted Answer

The repetition highlights Sarah as a direct recipient of God’s promised good, not an indirect beneficiary through Abraham. It also adds weight and certainty to the promise: the blessing is stated, then the son is promised, then the blessing is restated as the passage expands toward nations and kings. In a short unit like this, repetition functions like underlining: it signals what the author wants the reader to notice as central.

Question 5

How does the phrase “a son by her” shape the reader’s understanding of the promised heir?

Accepted Answer

“A son by her” ties the promised child specifically to Sarah as the mother and to this marriage as the line through which the promise will proceed. The text does not describe alternative ways of obtaining an heir; it specifies Sarah as the woman through whom the son will come. This matters in the Genesis storyline because the covenant promise is being narrowed to a particular child from a particular mother, not just any descendant of Abraham.

Question 6

What might “mother of nations” and “kings of peoples” communicate within an ancient household-and-lineage setting?

Accepted Answer

In an ancient setting where family continuity and status were closely tied to descendants, these phrases indicate an unusually expansive future. “Mother of nations” suggests Sarah’s descendants will branch into multiple peoples, not remain a small clan. “Kings of peoples” adds that political leadership will arise from her line. The text itself does not define the timeline, but the language implies the promise reaches beyond an immediate child to many generations and broad influence.
