A.T. Robertson Commentary Hebrews 11:19

"accounting that God [is] able to raise up, even from the dead; from whence he did also in a figure receive him back." — Hebrews 11:19 (ASV)

Accounting (λογισαμενος). First aorist middle participle of λογιζομα. Abraham had God's clear command that contravened God's previous promise. This was his solution of his difficult situation.

God is able (δυνατα ο θεος). God had given him Isaac in his old age. God can raise him from the dead. It was Abraham's duty to obey God.

In a parable (εν παραβολη). See already 9:9 for παραβολη. Because of (οθεν, whence) Abraham's superb faith Isaac was spared and so he received him back (εκομισατο) as almost from the dead. This is the test that Abraham stood of which James speaks (James 2:23).
