Genesis 17:1-21

Abraham and the Covenant of Circumcision

1When Abram was ninety-nine years old the Lord appeared to Abram and said to him, “I am God Almighty;
Hebrew El Shaddai
walk before me, and be cblameless,
2that I may make my covenant between me and you, and dmay multiply you greatly.” 3Then Abram efell on his face. And God said to him, 4Behold, my covenant is with you, and you shall be fthe father of a multitude of nations. 5No longer shall your name be called Abram,
 Abram means exalted father
but hyour name shall be Abraham,
 Abraham means father of a multitude
jfor I have made you the father of a multitude of nations.
6I will make you exceedingly fruitful, and I will make kyou into nations, and lkings shall come from you. 7And I will mestablish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, nto be God to you and to your offspring after you. 8And oI will give to you and to your offspring after you the land of your sojournings, all the land of Canaan, for an everlasting possession, and pI will be their God.”

9And God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. 10This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. 11You shall be circumcised in the flesh of your foreskins, and it shall be a qsign of the covenant between me and you. 12He who is reight days old among you shall be circumcised. Every male throughout your generations, whether born in your house or sbought with your money from any foreigner who is not of your offspring, 13both he who is born in your house and he who is bought with your money, shall surely be circumcised. So shall my covenant be in your flesh an everlasting covenant. 14Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”

Isaac’s Birth Promised

15And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah
 Sarai and  Sarah mean princess
shall be her name.
16I will bless her, and moreover, I will ugive
Hebrew have given
you a son by her. I will bless her, and wshe shall become nations; kings of peoples shall come from her.”
17Then Abraham xfell on his face yand laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” 18And Abraham said to God, “Oh that Ishmael might live before you!” 19God said, “No, but zSarah your wife shall bear you a son, and you shall call his name aaIsaac.
 Isaac means he laughs
I will establish my covenant with him as an everlasting covenant for his offspring after him.
20As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and acmultiply him greatly. He adshall father twelve princes, and aeI will make him into a great nation. 21But afI will establish my covenant with Isaac, agwhom Sarah shall bear to you at this time next year.”
