Galatia 4:22

4:22 For it is written that Abraham had two sons, one by the ¹  slave woman and the other by the free woman.

Ibrani 11:11

11:11 By faith, even though Sarah herself was barren and he was too old, ²  he received the ability to procreate, ³  because he regarded the one who had given the promise to be trustworthy.

[4:22]  ¹ tn Paul’s use of the Greek article here and before the phrase “free woman” presumes that both these characters are well known to the recipients of his letter. This verse is given as an example of the category called “well-known (‘celebrity’ or ‘familiar’) article” by ExSyn 225.

[11:11]  ² tn Grk “past the time of maturity.”

[11:11]  ³ 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.”
