John Wesley on Exodus 20:17

Thou shalt not covet - 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. God give us all to see our face in the glass of this law, and to lay our hearts under the government of it!
