In Genesis 18:13, the Lord directly quotes this promise back when questioning Sarah's laughter — it's the same announcement being affirmed and defended.

In Genesis 18:14, God presses the question: 'Is anything too hard for the Lord?' — grounding the promise of a son in divine omnipotence against human doubt.

In Genesis 17:16, God promises to bless Sarah and that nations and kings will come from her. This is the covenantal promise underlying the specific birth announcement here.

In Genesis 17:19, God names the promised child Isaac and says Sarah will bear him. This earlier revelation names and specifies what 18:10 now reiterates.

In Genesis 17:21, God already specified 'at this time next year' Sarah will bear Isaac. This verse echoes that earlier promise almost word-for-word, reinforcing its certainty.

Genesis 21:2 records the fulfillment: Sarah conceived and bore Isaac at the exact time God had spoken — directly answering this promise.

In Genesis 22:16, God's sworn oath follows Abraham offering Isaac — the very son promised here. The oath blesses Abraham 'because you have not withheld your son.'

In Genesis 21:1, God fulfills this promise as Sarah gives birth to Isaac.

In Genesis 16:2, Sarah's use of Hagar for a son precedes and contrasts with God's miraculous promise here.

In Genesis 24:36, the servant references Sarah's son Isaac, affirming the promise's fulfillment.

In Genesis 16:10, God also promises multiplied descendants — but to Hagar, not Sarah. Both are divine promises of offspring to women in Abraham's household, yet directed to different mothers.

In Luke 1:13, the angel's announcement to Zechariah mirrors this promise of a miraculous birth to an elderly couple.

In Romans 9:8, Paul explains that God's promise was carried through Isaac, affirming this prophecy's fulfillment.

In Romans 9:9, Paul directly quotes this promise to make a point about divine timing.

In Galatians 4:28, believers are called children of promise like Isaac, echoing this divine declaration.

In Judges 13:3-5, an angel announces Samson's birth to a barren woman. Both passages follow the pattern of a divine messenger promising a son to a childless couple.

In 2 Kings 4:14, the Shunammite woman likewise has no son and an aged husband, paralleling Sarah's situation before a miraculous birth is promised.

In Galatians 4:23, Paul contrasts the sons of the slave and free women, rooted in this promise to Sarah.

In 2 Kings 4:16, Elisha promises the Shunammite woman a son. Both involve a divine promise of a child to a woman — though here Sarah is old, while the Shunammite's husband is old.

In 2 Kings 4:17, the woman conceives and bears a son at the appointed time — mirroring the pattern of a barren woman receiving and fulfilling a divine promise of a child.

In Matthew 1:21, an angel announces that Mary will bear a son—echoing the divine birth-announcement pattern here, though the purpose differs greatly.
