Charles Spurgeon Commentary Exodus 20:12-14

"Honor thy father and thy mother, that thy days may be long in the land which Jehovah thy God giveth thee. Thou shalt not kill. Thou shalt not commit adultery." — Exodus 20:12-14 (ASV)

These commandments take a far wider sweep than the mere words. Thou shalt not kill includes the doing of anything by which life may be shortened as well as taken away. It includes anger – every evil wish and every malicious passion. And Thou shalt not commit adultery includes every form of unchastity and impurity.
