'Divorcement' in the Bible

When a man taketh a wife, and marrieth her, then it shall be, if she find no favor in his eyes, because he hath found some unseemly thing in her, that he shall write her a bill of divorcement, and give it in her hand, and send her out of his house.

And if the latter husband hate her, and write her a bill of divorcement, and give it in her hand, and send her out of his house; or if the latter husband die, who took her to be his wife;

Thus saith Jehovah, Where is the bill of your mother's divorcement, wherewith I have put her away? or which of my creditors is it to whom I have sold you? Behold, for your iniquities were ye sold, and for your transgressions was your mother put away.

And I saw, when, for this very cause that backsliding Israel had committed adultery, I had put her away and given her a bill of divorcement, yet treacherous Judah her sister feared not; but she also went and played the harlot.

It was said also, Whosoever shall put away his wife, let him give her a writing of divorcement:

They say unto him, Why then did Moses command to give a bill of divorcement, and to put her away?

And they said, Moses suffered to write a bill of divorcement, and to put her away.
