Episode 271 "Sarai get a new name and a crazy promise" - Genesis. 17:15-27
Gen. 17:15 And God said to Abraham, “As for Sarai your wife, you shall not call her name 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 become nations; kings of peoples shall come from her.” 17 Then Abraham fell on his face and 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?” 18 And Abraham said to God, “Oh that Ishmael might live before you!” 19 God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. 20 As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and multiply him greatly. He shall father twelve princes, and I will make him into a great nation. 21 But I will establish my covenant with Isaac, whom Sarah shall bear to you at this time next year.”
Gen. 17:22 When he had finished talking with him, God went up from Abraham. 23 Then Abraham took Ishmael his son and all those born in his house or bought with his money, every male among the men of Abraham’s house, and he circumcised the flesh of their foreskins that very day, as God had said to him. 24 Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. 25 And Ishmael his son was thirteen years old when he was circumcised in the flesh of his foreskin. 26 That very day Abraham and his son Ishmael were circumcised. 27 And all the men of his house, those born in the house and those bought with money from a foreigner, were circumcised with him.
This part begins with God changing another name. He had just changed Abram’s name to Abraham, and now he has changed Sarai’s name to Sarah. The difference is that the author explains the meaning of Abram and Abraham but does not explain the difference between Sarai and Sarah. Sarai means “Princess.” It’s possible that there is no significant difference in the meaning of the name change. Rather, the LORD changes it to signify her part in the covenant as the one who would bear the promised seed. It would be Sarah’s son who would inherit the covenant given to Abraham and not the son Ishmael born to Hagar. The LORD’s message to Abraham regarding Sarah echoes the promise the LORD had made to Abraham. It emphasizes that Sarah is the one through whom kings and nations would come and, more importantly, the descendants who would inherit the Abrahamic Covenant.
Verse 17 gives us Abraham’s response. He fell on his face and laughed. What a natural and appropriate response to being told that you would be able to beget a child at 100 years old and your wife would bear that child at ninety years of age. His thoughts, best summarized as “Is this really possible?” might make us wonder if he’s doubting the LORD. The LORD does not challenge him. So, I believe this is just a reasonable pondering in his mind of “How could this be?” Then, Abraham responds to God, suggesting that Ishmael fits the bill just fine with him.
It’s at this point that the LORD corrects him and tells him that he will have a son by Sarah, and they will name him Isaac. The meaning of this name is not given directly in the text. However, a word study reveals that this name may be associated with laughter. Since Abraham laughs at the thought of this child in their old age, and Sarah later laughs when she hears that she will have a son in her old age, the name may serve as a reminder of their response to the LORD’s providence in bringing about this miracle in their old age.
In verse 20, the LORD reveals that he will also bless Ishmael and bring nations through him. But Isaac is the son of the promise and will inherit the covenant God made with Abraham. We must see God’s mercy toward Hagar and Ishmael in these Scriptures.
Verses 22-27 can be summarized in one word, “Obedience.” Despite the illogical possibility of Abraham and Sarah having children at such an old age, Abraham responds to the LORD’s revelation by obeying the LORD and having every male in his household circumcised according to the LORD’s requirement for their participation in the covenant.
It seems to me the most evident lesson we can learn is to obey the LORD even when what we are doing may seem contrary to what we want to do or think. Maybe that is giving something to a homeless person. We think, Oh . . .they’ll just sell it to buy drugs or alcohol.” The LORD may not speak audibly to us or communicate through a dream. Yet, there may be a sense that we need to do something good, yet one part of us resists. If we know it’s not in conflict with God’s word, we’re free to step out on faith and act. We may laugh and wonder to ourselves if it’s worth it. But we can trust the LORD can use it however he wants.
