Song of Songs 8:6-7

6. Place me like a seal over your heart, like a seal on your arm; for love is as strong as death, its jealousy unyielding as the grave. It burns like blazing fire, like a mighty flame.
7. Many waters cannot quench love; rivers cannot wash it away. If one were to give all the wealth of his house for love, it would be utterly scorned.

Colossians 3:17-25

17. And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him.
18. Wives, submit to your husbands, as is fitting in the Lord.
19. Husbands, love your wives and do not be harsh with them.
20. Children, obey your parents in everything, for this pleases the Lord.
21. Fathers, do not embitter your children, or they will become discouraged.
22. Slaves, obey your earthly masters in everything; and do it, not only when their eye is on you and to win their favor, but with sincerity of heart and reverence for the Lord.
23. Whatever you do, work at it with all your heart, as working for the Lord, not for men,
24. since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.
25. Anyone who does wrong will be repaid for his wrong, and there is no favoritism.
