9 If my heart went after another man's wife, or if I was waiting secretly at my neighbour's door; 10 Then let my wife give pleasure to another man and let others make use of her body. 11 For that would be a crime; it would be an act for which punishment would be measured out by the judges: 12 It would be a fire burning even to destruction, and taking away all my produce. 13 If I did wrong in the cause of my man-servant, or my woman-servant, when they went to law with me; 14 What then will I do when God comes as my judge? and what answer may I give to his questions? 15 Did not God make him as well as me? did he not give us life in our mothers' bodies?

Matthew Henry's Commentary on Job 31:9-15

Commentary on Job 31:9-15

(Read Job 31:9-15)

All the defilements of the life come from a deceived heart. Lust is a fire in the soul: those that indulge it, are said to burn. It consumes all that is good there, and lays the conscience waste. It kindles the fire of God's wrath, which, if not quenched by the blood of Christ, will consume even to eternal destruction. It consumes the body; it consumes the substance. Burning lusts bring burning judgments. Job had a numerous household, and he managed it well. He considered that he had a Master in heaven; and as we are undone if God should be severe with us, we ought to be mild and gentle towards all with whom we have to do.
