the law of Yahweh is perfect

The law of Yahweh is perfect, reviving the soul; the testimony of Yahweh is sure, making wise the simple; the precepts of Yahweh are right, rejoicing the heart; the commandment of Yahweh is pure, enlightening the eyes; the fear of Yahweh is clean, enduring forever; the rules of Yahweh are true, and righteous altogether. More to be desired are they than gold, even much fine gold; sweeter also than honey and drippings of the honeycomb. Moreover, by them is your servant warned; in keeping them there is great reward.
(Psalms 19:7-11 ESV)
