John Gill Commentary Hebrews 6:15

"And thus, having patiently endured, he obtained the promise." — Hebrews 6:15 (ASV)

And so, after he had patiently endured
He waited long for a son, from whom the Messiah was to spring, after he had had the promise of one; and he endured many afflictions with patience, in his journeys from place to place, throughout his life to the end:

he obtained the promise ;
he was greatly blessed in temporal things; he lived to see the son of the promise, and his sons; he saw the day of Christ by faith, and now inherits the heavenly glory, which is the thing chiefly designed.
