Abraham sends his servant to get a wife for Isaac from their extended family in Nahor. He succeeds with God's help and Rebekah is willing to go. This is a LONG chapter, emphasizing the importance of a bride for Isaac.
How is this about Jesus?
God gets a bride for His Son, too - the Church.
God provides a way for the faithful remnant and lineage to succeed to future generations.
Sins this passage may reveal:
Unwillingness to leave comfort or family to follow God's will.
Too willing to compromise the right out of fear or doubt that God won't provide (Abraham could have kept a plan B in place to take a bride for Isaac from the Canaanites.)
