Then Abraham fell on his face and laughed and said in his heart, “Will a child be born to him who is 100 years old? Will Sarah, who is 90 years old, give birth?” Bible see other translations

“him who is 100.” The Hebrew is idiomatic: “to the son of 100 years.” The same is said of Sarah: “a daughter of 90 years.”
