Give to the wise, and they will be wiser still; teach the righteous, and they will add to their learning.
In context
7Whoever corrects a scoffer gets shame for himself, and whoever reproves a wicked man gets himself hurt. 8Do not reprove a scoffer, or he will hate you; reprove a wise man, and he will love you. 9Give to the wise, and they will be wiser still; teach the righteous, and they will add to their learning. 10The beginning of wisdom is the fear of Yahweh, and knowledge of the Holy One is understanding. 11For through me your days will be many, and years of life will be added to you.
