Genesis 17:15 Meaning and Commentary

Genesis 17:15

And God said unto Abraham
After he had changed his name, and given him the covenant of circumcision:

as for Sarai thy wife, thou shalt not call her name Sarai, but Sarah
her name [shall be];
her former name Sarai signifies "my princess", or rather "princesses", being to him in the room of many, and better than ten thousand; yet only a princess to him, and in his family, being sole mistress there: but Sarah signifies, as Jarchi observes, "princess" absolutely, because she was princess over all the princes and people that should come of her, as well as be the mother and princess of all female believers, who are called her daughters, ( 1 Peter 3:6 ) .

Genesis 17:15 In-Context

13 {You must certainly circumcise} {the servant born in your house and the one bought from any foreigner}. And my covenant shall be with your flesh as an everlasting covenant.

14 And [as for any] uncircumcised male who has not circumcised the flesh of his foreskin, that person shall be cut off from his people. He has broken my covenant.

15 And God said to Abraham, "[as for] Sarai your wife, you shall not call her name Sarai, for Sarah [shall be] her name.

16 And I will bless her; moreover, I give to you from her a son. And I will bless her, and {she shall give rise to nations}. Kings of peoples shall come from her."

17 And Abraham fell upon his face and laughed. And he said in his heart, "{Can a child be born to a man a hundred years old}, or {can Sarah bear a child at ninety}?"
