Give instruction to a wise man and he will become even wiser;
teach a righteous man and he will increase in learning. Bible see other translations

“Give instruction to.” The Hebrew is simply “Give to,” requiring the reader to supply the subject from the context, which is “teach” in the second stanza. Although we filled in the subject with “instruction,” which is no doubt the primary meaning, the fact that the Hebrew text leaves the subject out alerts us to be aware of the many things we could give to the righteous man so he would continue to be wise, including reproof and correction.
