(Psalms 15:1-5) <<A Psalm of David.>> LORD, who may abide in Your tabernacle? Who may dwell in Your holy hill? He who walks uprightly, And works righteousness, And speaks the truth in his heart; He who does not backbite with his tongue, Nor does evil to his neighbor, Nor does he take up a reproach against his friend; In whose eyes a vile person is despised, But he honors those who fear the LORD; He who swears to his own hurt and does not change; He who does not put out his money at usury, Nor does he take a bribe against the innocent. He who does these things shall never be moved. (NKJV)
This Psalms Thomas Jefferson would refer to the youth. He knew that it would benefit them if they were wise enough to live by its precepts.
