Genesis 19:30-38 English Standard Version
Lot and His Daughters
30 Now Lot went up out of Zoar and lived in the hills with his two daughters, for he was afraid to live in Zoar. So he lived in a cave with his two daughters. 31 And the firstborn said to the younger, “Our father is old, and there is not a man on earth to come in to us after the manner of all the earth. 32 Come, let us make our father drink wine, and we will lie with him, that we may preserve offspring from our father.” 33 So they made their father drink wine that night. And the firstborn went in and lay with her father. He did not know when she lay down or when she arose.
34 The next day, the firstborn said to the younger, “Behold, I lay last night with my father. Let us make him drink wine tonight also. Then you go in and lie with him, that we may preserve offspring from our father.” 35 So they made their father drink wine that night also. And the younger arose and lay with him, and he did not know when she lay down or when she arose. 36 Thus both the daughters of Lot became pregnant by their father. 37 The firstborn bore a son and called his name Moab. He is the father of the Moabites to this day. 38 The younger also bore a son and called his name Ben-ammi. He is the father of the Ammonites to this day.
This was the source of this edict. Deuteronomy 23:3 “No Ammonite or Moabite may enter the assembly of the Lord. Even to the tenth generation, none of them may enter the assembly of the Lord forever,”
Matthew 1:5 and Salmon the father of Boaz by Rahab, and Boaz the father of Obed by Ruth, and Obed the father of Jesse,
Ruth, a Moabite, is in the lineage of Jesus just three generations before King David. Did Boaz violate an edict from Moses? Ruth was the daughter by law of Naomi who was of the tribe of Benjamin. Since Ruth rejected her lineage and clung to Naomi, was she still a Moabite?
Perhaps Boaz had a different point of view because his mother was Rahab, the harlot from Joshua 2:1. She was saved in the collapse of Jericho because she helped two spies by hiding them in accordance with Joshua 6:17.
The source of our opinions are many and before we go about name calling, perhaps we should understand their history. Remember our Lord was called a blasphemer by the Pharisees. John the Baptist called them vipers, that was ugly.
Matthew 23:13 “But woe to you, scribes and Pharisees, hypocrites! For you shut the kingdom of heaven in people’s faces. For you neither enter yourselves nor allow those who would enter to go in.”
At least when Jesus called them hypocrites, He gave examples of their offenses.
