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 The slave born in your house and the person bought with your money must be circumcised; thus my covenant will be in your flesh as an everlasting covenant.

14 Any uncircumcised male who will not let himself be circumcised in the flesh of his foreskin -that person will be cut off from his people, because he has broken my covenant."

15 God said to Avraham, "As for Sarai your wife, you are not to call her Sarai [mockery]; her name is to be Sarah [princess].

16 I will bless her; moreover, I will give you a son by her. Truly I will bless her: she will be a mother of nations; kings of peoples will come from her."

17 At this Avraham fell on his face and laughed - he thought to himself, "Will a child be born to a man a hundred years old? Will Sarah give birth at ninety?"
