Hebrews 11:8

11:8 By faith Abraham obeyed when he was called to go out to a place he would later receive as an inheritance, and he went out without understanding where he was going.

Hebrews 11:17

11:17 By faith Abraham, when he was tested, offered up Isaac. He had received the promises, yet he was ready to offer up his only son.

tn Here “received the promises” refers to the pledges themselves, not to the things God promised.

tn Grk “he was offering up.” The tense of this verb indicates the attempt or readiness to sacrifice Isaac without the actual completion of the deed.
