Leviticus 15:4

Every bed whereon he lieth that hath the flux shall be unclean; and every object on which he sitteth shall be unclean.

Be not deceived: evil communications corrupt good manners.

and do not have fellowship with the unfruitful works of darkness, but rather also reprove them,

All things are pure to the pure; but to the defiled and unbelieving nothing is pure; but both their mind and their conscience are defiled.

Every bed, whereon he lieth that hath the issue, is unclean: and every thing, whereon he sitteth, shall be unclean.

Be not deceived: evil communications corrupt good manners.

and do not have fellowship with the unfruitful works of darkness, but rather also reprove them,

All things are pure to the pure; but to the defiled and unbelieving nothing is pure; but both their mind and their conscience are defiled.

And everything that she lieth upon in her separation shall be unclean; and everything that she sitteth upon shall be unclean.
