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 He who is born in your house, and he who is bought with your money, must be circumcised. My covenant will be in your flesh for an everlasting covenant.

14 The uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people. He has broken my covenant."

15 God said to Avraham, "As for Sarai your wife, you shall not call her name Sarai, but her name will be Sarah.

16 I will bless her, and moreover I will give you a son by her. Yes, I will bless her, and she will be a mother of nations. Kings of peoples will come from her."

17 Then Avraham fell on his face, and laughed, and said in his heart, "Will a child be born to him who is one hundred years old? Will Sarah, who is ninety years old, give birth?"
