Deuteronomy 24:4
her first man which sent her away may not take her again to be his wife, inasmuch as she is defiled. For that is abomination in the sight of the LORD: that thou defile not the land with sin, which the LORD thy God giveth thee to inherit.
Jeremiah 3:1
Commonly, when a man putteth away his wife, and she goeth from him, and marrieth with another, then the question is: should he resort unto her any more after that? Is not this field then defiled and unclean? But as for thee, thou hast played the harlot with many lovers, yet turn again to me, sayeth the LORD.
Leviticus 18:24-28
Defile not yourselves in any of these things, for with all these things are these nations defiled which I cast out before you:
Joshua 22:17-18
Is the wicked deed of Peor too little for us, whereof we are not cleansed unto this day, and there was a plague in the congregation of the LORD?
