'Adultery' in the Bible

And he saith unto them, Whosoever shall put away his wife, and marry another, committeth adultery against her:

and if she herself shall put away her husband, and marry another, she committeth adultery.

Thou knowest the commandments, Do not kill, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor thy father and mother.
