'Sexual' in the Bible

but I tell you that whoever puts away his wife, except for the cause of sexual immorality, makes her an adulteress; and whoever marries her when she is put away commits adultery.

For out of the heart come forth evil thoughts, murders, adulteries, sexual sins, thefts, false testimony, and blasphemies.

I tell you that whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and he who marries her when she is divorced commits adultery."
