And the children struggled together within her; and she said, If it be so, why am I thus? And she went to enquire of the Lord.
Cross-reference
Genesis 27:29 shows the eventual outcome of the struggle: nations serving Jacob. This is the fulfillment of the oracle given here about the older serving the younger.
In Romans 9:12, Paul quotes the oracle given here to show God's sovereign choice before birth—'the older will serve the younger.'
In Ezekiel 36:37, God invites Israel to inquire of Him for restoration, echoing Rebekah's act of inquiring. Both frame inquiry as a response to divine promise.
In 1 Samuel 9:9, 'inquiring of God' via a seer was common practice — illuminating the cultural background of Rebekah's decision to seek the LORD directly.
In 1 Samuel 28:6, Saul inquired of the LORD but received no answer, unlike Rebekah who inquired and received an oracle. Both involve seeking divine guidance in distress.
In 1 Samuel 30:8, David inquired of the LORD and received a direct answer, like Rebekah. Both show successful divine inquiry in a moment of crisis.
