Bible Verses about Marriage

“And He answered and said to them, ‘Have you not read that He who made them at the beginning ‘made them male and female,’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh?’ So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.'”
(Matthew 19:4-6, NKJV)
“‘But from the beginning of the creation, God ‘made them male and female.’ ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh‘; so then they are no longer two, but one flesh. Therefore what God has joined together, let not man separate.'”
(Mark 10:7-9, NKJV)
“Or do you not know that he who is joined to a harlot is one body with her? For ‘the two,’ He says, ‘shall become one flesh.'”
(1 Corinthians 6:16, NKJV)
“‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.’ This is a great mystery, but I speak concerning Christ and the church. Nevertheless let each one of you in particular so love his own wife as himself, and let the wife see that she respects her husband.”
(Ephesians 5:31-33, NKJV)
