Ge 20:12—How was Sarah Abraham’s sister? (wp17.3 12, ftn.)

Sarah was the half sister of Abraham. Terah was father to both of them, but they had different mothers. (Genesis 20:12) While such a marriage is improper today, it is important to keep in mind how different things were back then. Humans were closer to the perfection that Adam and Eve had enjoyed but lost. For such robust people, marriage between close relatives evidently did not present genetic dangers to offspring. Some 400 years later, though, life spans were similar to ours. At that time, the Mosaic Law outlawed all sexual unions between close relatives.—Leviticus 18:6.

Ge 21:33—How did Abraham call “on the name of Jehovah”? (w89 7/1 20 ¶9)

9 Abram responded with another act of faith. As the account says: “He built an altar there to Jehovah.” (Genesis 12:7) Likely, this included offering up an animal sacrifice, for the Hebrew word for “altar” means “place of sacrifice.” Later, Abram repeated these acts of faith in other parts of the land. In addition, he ‘called on the name of Jehovah.’ (Genesis 12:8;13:18; 21:33) The Hebrew phrase “call on the name” also means “declare (preach) the name.” Abram’s household as well as the Canaanites must have heard him boldly declare the name of his God, Jehovah. (Genesis 14:22-24) Likewise, all who seek God’s friendship today must call upon his name in faith. This would include sharing in public preaching, “always offer[ing] to God a sacrifice of praise, that is, the fruit of lips which make public declaration to his name.”—Hebrews 13:15; Romans 10:10.
