Hebrews 11:11

11:11 By faith, even though Sarah herself was barren and he was too old, ¹  he received the ability to procreate, ²  because he regarded the one who had given the promise to be trustworthy.

Hebrews 11:17-18

11:17 By faith Abraham, when he was tested, offered up Isaac. He had received the promises, ³  yet he was ready to offer up ⁴  his only son. 11:18 God had told him, “Through Isaac descendants will carry on your name,” ⁵ 

¹ tn Grk “past the time of maturity.”

² tn Grk “power to deposit seed.” Though it is not as likely, some construe this phrase to mean “power to conceive seed,” making the whole verse about Sarah: “by faith, even though Sarah herself was barren and too old, she received ability to conceive, because she regarded the one who had given the promise to be trustworthy.”

³ tn Here “received the promises” refers to the pledges themselves, not to the things God promised.

⁴ 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.

⁵ tn Grk “in Isaac seed will be named for you.”
