The two brothers who could not be more different from each other. One was a ladies’ man while the other was a lady like man. Esau was a hairy individual who loved the outdoors while Jacob was content managing the household chores. But Jacob was chosen by God to continue the lineage leading to Jesus while Esau had to be content with his bowl of soup.
We saw in the last chapter that God had enabled everyone in Abimelek’s household to conceive again but Sarah was still kept barren. Abraham had laughed at the very thought of Isaac being born to Sarah, Sarah now has joyous laughter that God came through for her despite her disbelief and then there is Ishmael who is mocking his new younger brother. The Hebrew texts quite aptly say that Ishmael was laughing at Isaac. That captures the sentiment of everyone involved in this saga.
I like the NIV heading as it doesn’t mention Abram or Sarai and just reads ‘Hagar and Ishmael’. Not surprising, given that this chapter reveals more details about the chosen family that we generally would not associate with the father of faith.
