“You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or his male servant, or his female servant, or his ox, or his donkey, or anything that is your neighbor’s.” Exodus 20:17 (ESV)

Matthew Henry’s Commentary:

VI. The tenth commandment strikes at the root: Thou shalt not covet, Exodus 20:17. The foregoing commands implicitly forbid all desire of doing that which will be an injury to our neighbour; this forbids all inordinate desire of having that which will be a gratification to ourselves. “O that such a man’s house were mine! Such a man’s wife mine! Such a man’s estate mine!” This is certainly the language of discontent at our own lot, and envy at our neighbour’s; and these are the sins principally forbidden here. St. Paul, when the grace of God caused the scales to fall from his eyes, perceived that this law, Thou shalt not covet, forbade all those irregular appetites and desires which are the first-born of the corrupt nature, the first risings of the sin that dwelleth in us, and the beginnings of all the sin that is committed by us: this is that lust which, he says, he had not known the evil of, if this commandment, when it came to his conscience in the power of it, had not shown it to him, Romans 7:7. God give us all to see our face in the glass of this law, and to lay our hearts under the government of it! [Emphasis Added]
