Exodus 20:14 Thou shalt not commit adultery.
[Patriarchs & Prophets pp 308>309] This commandment forbids not only acts of impurity, but sensual thoughts and desires, or any practice that tends to excite them. Purity is demanded not only in the outward life but in the secret intents and emotions of the heart. Christ, who taught the far-reaching obligation of the law of God, declared the evil thought or look to be as truly sin as is the unlawful deed. “Thou shalt not steal.” Both public and private sins are included in this prohibition. The eighth commandment condemns man-stealing and slave dealing, and forbids wars of conquest.
It condemns theft and robbery. It demands strict integrity in the minutest details of the affairs of life. It forbids overreaching in trade, and requires the payment of just debts or wages. It declares that every attempt to advantage oneself by the ignorance, weakness, or misfortune of another is registered as fraud in the books of heaven. “Thou shalt not bear false witness against thy neighbor.” False speaking in any matter, every attempt or purpose to deceive our neighbor, is here included. An intention to deceive is what constitutes falsehood.
By a glance of the eye, a motion of the hand, an expression of the countenance, a falsehood may be told as effectually as by words. All intentional overstatement, every hint or insinuation calculated to convey an erroneous or exaggerated impression, even the statement of facts in such a manner as to mislead, is falsehood. This precept forbids every effort to injure our neighbor's reputation by misrepresentation or evil surmising, by slander or tale bearing. Even the intentional suppression of truth, by which injury may result to others, is a violation of the ninth commandment.
Proverbs 12:22 Lying lips are abomination to the Lord: but they that deal truly are his delight.
May The Lord add His blessing to the study of His word. God bless!
