Job 31:12

For it is a fire that consumeth to destruction, and would root out all mine increase.

For it is a fire that consumeth to destruction,.... Referring either to the nature of the sin of uncleanness; it is inflammatory, a burning lust, a fire burning in the breast; see 1 Corinthians 7:9; or to the effect of it, either the rage of jealousy in the injured person, which is exceeding fierce, furious, and cruel, like devouring fire, not to be appeased or mitigated, Proverbs 6:34; or else it may respect the punishment of this sin in the times of Job, and which we find was practised among the Gentiles, as the Canaanites, Job's neighbours, burning such delinquents with fire; see Genesis 38:24; or rather the wrath of God for it, which is poured forth as fire, and burns to the lowest hell, and into which lake of fire all such impure persons will be cast, unless the grace of God prevents; and which will be a fire that will consume and destroy both soul and body, and so be an utter and everlasting destruction,

Revelation 21:8;

and would root out all my increase; even in this world; adultery is a sin that not only ruins a man's character, fixes an indelible blot upon him, a reproach that shall not be wiped off, and consumes a man's body, and destroys the health of it, but his substance also, the increase of his fields, and of his fruits, and by means of it a man is brought to a piece of bread, to beg it, and to be glad of it, Proverbs 6:26.
