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, and My covenant shall be in your flesh for an everlasting covenant.

14 And the uncircumcised male child, who is not circumcised in the flesh of his foreskin, that person shall be cut off from his people; he has broken My covenant."

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

16 And I will bless her and also give you a son by her; then I will bless her, and she shall be a mother of nations; kings of peoples shall be from her."

17 Then Abraham fell on his face and laughed, and said in his heart, "Shall a child be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, bear a child?"
