Psalms 119:66

Good judgment; whereby I may rightly discern between truth and falsehood, good and evil, between the mind of God and my own or others inventions; that so I may be kept from those mistakes and errors in which many are involved, that I may truly judge what thy law requires or permits, and what it forbids. Heb. the goodness of taste, an experimental sense and relish of divine things. Compare Psalms 34:8. Knowledge; a spiritual and experimental knowledge. And judgment, or taste, and knowledge may, by a usual figure called hendiadis, be put for judicious, or solid, or practical knowledge. I have believed thy commandments; I have believed the Divine authority of them, and the truth and certainty of those promises and threatenings which thou hast annexed to them.
