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 Both the slave born in your house and the one bought with your money must be circumcised. So shall my covenant be in your flesh an everlasting covenant.
14 Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant."
15 God said to Abraham, "As for Sarai your wife, you shall not call her Sarai, but Sarah shall be her name.
16 I will bless her, and moreover I will give you a son by her. I will bless her, and she shall give rise to nations; kings of peoples shall come from her."
17 Then Abraham fell on his face and laughed, and said to himself, "Can a child be born to a man who is a hundred years old? Can Sarah, who is ninety years old, bear a child?"
