I can’t quite peg Abraham’s laughter. Disbelief or wonder? In either case, the fact that he “recovered” (the message) to check to make sure Ishmael would live tips to Abraham’s general state of piety.

This is the third time God’s spelled out that Abraham would father a nation. Each time the proclamation has come at greater cost though—I imagine Hagar was mortified that Ishmael was Abraham’s promised descendant. I imagine Abraham and Sarah felt a sting of shame that they tried forcing God’s hand earlier. I think recognizes Abraham’s steady struggle with doubt when he tells Abraham when Isaac will be born. My guess is that without that, a few weeks without sign of pregnancy and Abraham wouldn’t been scouring the countryside for other women named Sarah that God must’ve really been talking about.
