'Marry' in the Bible

Now about what you asked: "Is it advisable for a man not to marry?"

But if they cannot contain, let them marry: for it is better to marry than to burn.

But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you.

But if any man think that he behaveth himself uncomely toward his virgin, if she pass the flower of her age, and need so require, let him do what he will, he sinneth not: let them marry.

So then he who marries his virgin does well, but he who does not marry will do better.

A wife is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, only in the Lord.
