I have some questions for those participating in this thread (or for those who are viewing it and haven't yet participated) who seek to differentiate between Israelites/Jews and Gentiles as if there are different standards which apply to different groups of people in relation to adultery. Here we go:
Genesis chapter 12
[10] And there was a famine in the land: and Abram went down into Egypt to sojourn there; for the famine was grievous in the land.
[11] And it came to pass, when he was come near to enter into Egypt, that he said unto Sarai his wife, Behold now, I know that thou art a fair woman to look upon:
[12] Therefore it shall come to pass, when the Egyptians shall see thee, that they shall say, This is his wife: and they will kill me, but they will save thee alive.
[13] Say, I pray thee, thou art my sister: that it may be well with me for thy sake; and my soul shall live because of thee.
[14] And it came to pass, that, when Abram was come into Egypt, the Egyptians beheld the woman that she was very fair.
[15] The princes also of Pharaoh saw her, and commended her before Pharaoh: and the woman was taken into Pharaoh's house.
[16] And he entreated Abram well for her sake: and he had sheep, and oxen, and he asses, and menservants, and maidservants, and she asses, and camels.
[17] And the LORD plagued Pharaoh and his house with great plagues because of Sarai Abram's wife.
[18] And Pharaoh called Abram, and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife?
[19] Why saidst thou, She is my sister? so I might have taken her to me to wife: now therefore behold thy wife, take her, and go thy way.
[20] And Pharaoh commanded his men concerning him: and they sent him away, and his wife, and all that he had.
What was THAT all about?
I mean, here we've got Abram and Sarai, BOTH GENTILES, and Pharaoh, ANOTHER GENTILE, right?
Well, why did God "plague Pharaoh and his house with great plagues because of Sarai Abram's wife"?
Was it not in relation to potential ADULTERY in that Pharaoh took another man's wife while her husband was yet alive?
And what about this:
Genesis chapter 20
[1] And Abraham journeyed from thence toward the south country, and dwelled between Kadesh and Shur, and sojourned in Gerar.
[2] And Abraham said of Sarah his wife, She is my sister: and Abimelech king of Gerar sent, and took Sarah.
[3] But God came to Abimelech in a dream by night, and said to him, Behold, thou art but a dead man, for the woman which thou hast taken; for she is a man's wife.
[4] But Abimelech had not come near her: and he said, Lord, wilt thou slay also a righteous nation?
[5] Said he not unto me, She is my sister? and she, even she herself said, He is my brother: in the integrity of my heart and innocency of my hands have I done this.
[6] And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me: therefore suffered I thee not to touch her.
[7] Now therefore restore the man his wife; for he is a prophet, and he shall pray for thee, and thou shalt live: and if thou restore her not, know thou that thou shalt surely die, thou, and all that are thine.
[8] Therefore Abimelech rose early in the morning, and called all his servants, and told all these things in their ears: and the men were sore afraid.
[9] Then Abimelech called Abraham, and said unto him, What hast thou done unto us? and what have I offended thee, that thou hast brought on me and on my kingdom a great sin? thou hast done deeds unto me that ought not to be done.
[10] And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing?
[11] And Abraham said, Because I thought, Surely the fear of God is not in this place; and they will slay me for my wife's sake.
[12] And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.
[13] And it came to pass, when God caused me to wander from my father's house, that I said unto her, This is thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He is my brother.
[14] And Abimelech took sheep, and oxen, and menservants, and womenservants, and gave them unto Abraham, and restored him Sarah his wife.
[15] And Abimelech said, Behold, my land is before thee: dwell where it pleaseth thee.
[16] And unto Sarah he said, Behold, I have given thy brother a thousand pieces of silver: behold, he is to thee a covering of the eyes, unto all that are with thee, and with all other: thus she was reproved.
[17] So Abraham prayed unto God: and God healed Abimelech, and his wife, and his maidservants; and they bare children.
[18] For the LORD had fast closed up all the wombs of the house of Abimelech, because of Sarah Abraham's wife.
???
Isn't this the same scenario?
I mean, once again, we've got Abraham and Sarah, BOTH GENTILES, and Abimelech, king of Gerar, himself A GENTILE, and God not only tells Abimelech that He's going to KILL HIM AND ALL THAT ARE HIS if he doesn't return another man's wife back to him, but He also closes up all the wombs of the house of Abimelech BECAUSE OF ABRAHAM'S WIFE.
Yes, even Abimelech acknowledged that he had been deceived into potentially committing "A GREAT SIN" (Genesis 20:9)
Folks, they were all GENTILES and this was also pre-law (of Moses).
Again, the "one flesh" union between a man and his wife was ordained by God way back in Genesis chapter 2 while there were yet only two people, Adam and Eve, BOTH GENTILES (unless anybody here wants to attempt to prove that they were Israelites/Jews...good luck with that), upon the face of the earth, so this whole, "Well, that doesn't apply to me because I'm not a Jew" and "Well, that doesn't apply to me because Paul was the teacher of the Gentiles" nonsense is just that:
NONSENSE!
Speaking of GENTILES, why was John the Baptist beheaded (I'm not saying that John the Baptist was a Gentile, but rather asking why A GENTILE, Herod, had him beheaded)? Well, there's no need to guess:
Mark chapter 6
[14] And king Herod heard of him; (for his name was spread abroad): and he said, That John the Baptist was risen from the dead, and therefore mighty works do shew forth themselves in him.
[15] Others said, That it is Elias. And others said, That it is a prophet, or as one of the prophets.
[16] But when Herod heard thereof, he said, It is John, whom I beheaded: he is risen from the dead.
[17] For Herod himself had sent forth and laid hold upon John, and bound him in prison for Herodias' sake, his brother Philip's wife: for he had married her.
[18] For John had said unto Herod, It is not lawful for thee to have thy brother's wife.
[19] Therefore Herodias had a quarrel against him, and would have killed him; but she could not:
[20] For Herod feared John, knowing that he was a just man and an holy, and observed him; and when he heard him, he did many things, and heard him gladly.
[21] And when a convenient day was come, that Herod on his birthday made a supper to his lords, high captains, and chief estates of Galilee;
[22] And when the daughter of the said Herodias came in, and danced, and pleased Herod and them that sat with him, the king said unto the damsel, Ask of me whatsoever thou wilt, and I will give it thee.
[23] And he sware unto her, Whatsoever thou shalt ask of me, I will give it thee, unto the half of my kingdom.
[24] And she went forth, and said unto her mother, What shall I ask? And she said, The head of John the Baptist.
[25] And she came in straightway with haste unto the king, and asked, saying, I will that thou give me by and by in a charger the head of John the Baptist.
[26] And the king was exceeding sorry; yet for his oath's sake, and for their sakes which sat with him, he would not reject her.
[27] And immediately the king sent an executioner, and commanded his head to be brought: and he went and beheaded him in the prison,
[28] And brought his head in a charger, and gave it to the damsel: and the damsel gave it to her mother.
[29] And when his disciples heard of it, they came and took up his corpse, and laid it in a tomb.
John the Baptist told king Herod who was an IDUMEAN or an EDOMITE (IOW, he was a NON-JEW) that "It is NOT LAWFUL for thee to have thy brother's wife" (Mark 6:18) and the same ultimately led to his beheading.
Now wait a minute...
What the heck was John the Baptist doing PREACING THE LAW TO A GENTILE?
Well, contrary to commonplace erroneous opinions of many a professing Christian nowadays, God's laws in relation to adultery (and a whole host of other things, too) ALWAYS applied to GENTILES as much as they applied to Israelites/Jews. In fact, the latter (Israelites/Jews) were supposed to be teaching the same to the former (the GENTILES) and people like John the Baptist and Jesus Christ REGULARLY DID...as did all of the prophets who came before them.
Anyhow, it wasn't "lawful" for Herod to take his brother Philip's wife BECAUSE HIS BROTHER PHILIP WAS STILL ALIVE AT THIS POINT IN TIME AND THIS ACT THEREFORE CONSTITUTED ADULTERY.
Let's all keep these things in mind as we go forward with this discussion, okay?
