There are over 500 verses in the Bible as a whole related to marriage. Here are just ten of them. Some of them may surprise you, some of them may challenge you, hopefully all of them will provide encouragement, insight and wisdom.
Genesis 2:18, 21-24
And the Lord God said, ‘It is not good that man should be alone; I will make him a helper comparable to him’….And the Lord God caused a deep sleep to fall on Adam, and he slept; and He took one of his ribs, and closed up the flesh in its place. Then the rib which the Lord God had taken from man He made into a woman, and He brought her to the man. And Adam said: ‘This is now bone of my bones, And flesh of my flesh; She shall be called Woman, Because she was taken out of Man.’ Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.
1 Corinthians 7:1-2
It is good for a man not to touch a woman. Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband.
For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.
Marriage is honorable among all, and the bed undefiled; but fornicators and adulterers God will judge.
Wives, submit to your own husbands, as to the Lord. For the husband is head of the wife, as also Christ is head of the church; and He is the Savior of the body. Therefore, just as the church is subject to Christ, so let the wives be to their own husbands in everything. Husbands, love your wives, just as Christ also loved the church and gave Himself for her
If he comes in by himself, he shall go out by himself; if he comes in married, then his wife shall go out with him.
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.
Wives, submit to your own husbands, as is fitting in the Lord. Husbands, love your wives and do not be bitter toward them.
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.”
So husbands ought to love their own wives as their own bodies; he who loves his wife loves himself.
