Matthew Poole and continuators on Hebrews 6:15

15 And so after he had patiently endured , he obtained the promise .

Abraham's Carriage was suitable to this sworn Promise, his Soul did patiently wait for it full Thirty Years, enduring and suffering many Temptations about it; yet he overcame all, and continued firm in the Covenant to the end; his Faith extended his Soul in a patient expectation of its accomplishment, without doubting or murmuring, knowing God would fulfil it in the best time; he was a long-breathed Believer, Iohn 8.56. Rom. 4.20, 21. and Iames 1.2, 3.

He did not fall short of any piece of the Promise, but fully possessed it at last, both in Isaac, the Type of the blessed Seed, and the Messiah himself, as to all the Spiritual and Eternal Good promised in him and by him in the Heavenly Canaan, Matth. 22.32.
