Mark 10:12

and if a woman puts away her husband and marries another, she commits adultery.

and also if she is separated let her remain unmarried or be reconciled to the husband, and let not a husband leave his wife.

and if any wife has an unbelieving husband and he is pleased to live with her, let her not leave the husband.

Treasury of Scripture Knowledge

And if a woman shall put away her husband, and be married to another, she committeth adultery.

Every one that puts away his wife and marries another, commits adultery; and he that marries a woman put away from a husband, commits adultery.

The wife has not the right to her body, but the husband; and in like manner the husband has not the right to his body, but the wife.
