Genesis 2:18-25 And YAHUAH Aluahim said, “It is not good for the man to be alone, I am going to make a helper for him, as his counterpart.” (19) And from the ground YAHUAH Aluahim formed every beast of the field and every bird of the heavens, and brought them to the man to see what he would call them. And whatever the man called each living creature, that was its name. (20) So the man gave names to all livestock, and to the birds of the heavens, and to every beast of the field. But for the man there was not found a helper for him, as his counterpart. (21) So YAHUAH Aluahim caused a deep sleep to fall on the man, and he slept. And He took one of his ribs, and closed up the flesh in its place. (22) And the rib which YAHUAH Aluahim had taken from the man He made into a woman, and He brought her to the man. (23) And the man said, “This is now bone of my bones and flesh of my flesh. This one is called ‘woman,’ because she was taken out of man.” (24) For this cause a man shall leave his father and mother, and cleave to his wife, and they shall become one flesh. (25) And they were both naked, the man and his wife, yet they were not ashamed.
Matatyahu 19:1-6 And it came to be, when YAHUSHUA had ended these words, that He left Galil and came to the borders of Yahudah beyond the Yuradan (Jordan). (2) And large crowds followed Him, and He healed them there. (3) And the Pharisees came to Him, trying Him, and saying to Him, “Is it right for a man to put away his wife for every reason?” (4) And He answering, said to them, “Did you not read that He who made them at the beginning made them male and female, (5) and said, ‘For this cause a man shall leave his father and mother and cleave to his wife, and the two shall become one flesh’? (6) “So that they are no longer two, but one flesh. Therefore, what Aluahim has joined together, let man not separate.”
Mark 10:1-9 And rising up from there He came into the borders of Yahudah by the other side of the Yuradan. And crowds gathered to Him again, and as He usually did, He was teaching them again. (2) And Pharisees came and asked Him, “Is it right for a man to put away his wife?” – trying Him. (3) And He answering, said to them, “What did Mushah command you?” (4) And they said, “Mushah allowed a man to write a certificate of divorce, and to put her away.” (5) And YAHUSHUA said to them, “Because of the hardness of your heart he wrote you this command. (6) “However, from the beginning of the creation, Aluahim ‘made them male and female.’ (7) ‘For this cause a man shall leave his father and mother and cleave to his wife, (8) and the two shall become one flesh,’ so that they are no longer two, but one flesh. (9) “Therefore what Aluahim has joined together, let man not separate.”
Ephesians 5:28-31 In this way husbands ought to love their own wives as their own bodies. He who loves his wife loves himself. (29) For no one ever hated his own flesh, but feeds and cherishes it, as also the Master does the assembly. (30) Because we are members of His body, of His flesh and of His bones. (31) “For this cause a man shall leave his father and mother and cleave to his wife, and the two shall become one flesh.”
