Proverbs 24:9

“The thoughts of foolishness [is] sin, etc.] The thought of sin is sinf655, before it comes into action; the motions of sin in the mind, the workings of corrupt nature in the heart, the sinful desires of the flesh and of the mind: these are forbidden and condemned by the law of God as sin, which says, “Thou shall not covet”, (<022017>Exodus 20:17), and stand in need of pardoning grace and mercy; (see <450705>Romans 7:5,7 <440822>Acts 8:22).
