Hebrews 11:17

11:17 By faith Abraham, when he was tested, offered up Isaac. He had received the promises, ¹  yet he was ready to offer up ²  his only son.

Hebrews 8:3

8:3 For every high priest is appointed to offer both gifts and sacrifices. So this one too had to have something to offer.

[11:17]  ¹ tn Here “received the promises” refers to the pledges themselves, not to the things God promised.

[11:17]  ² 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.
