He keepeth the paths of judgment, and preserveth the way of his saints.
He keepeth the paths of judgment - Hebrew, 'so as that [li-] He may keep the paths of judgment' - i:e., that He may cause the upright to keep the paths of judgment-that they may have a right judgment in all things. This is the end for which He is a "buckler" to them (Proverbs 2:7).
And preserveth the way of his saints. This is the secret of their 'walking uprightly' (Proverbs 2:7), which they could not do of themselves. "Saints" - Hebrew, chasidaiv; literally, the merciful (those who have obtained mercy, and so are merciful), the pious, the godly (Psalms 91:11; 27:23-24; 1 Samuel 2:9, "He will keep the feet of his saints").
