Receive, I pray thee, the law from his mouth, and lay up his words in thine heart.

Wesley's Notes

22:22 Receive - Take the rule whereby thou governest thy thoughts, and words, and whole life, not from thy own imaginations or passions, but from God, from his law, which is written in thy own mind, and from the doctrines and instructions of the holy men of God. And do not only hear them with thine ears, but let them sink into thy heart.

Matthew Henry's Concise Commentary

22:21-30 The answer of Eliphaz wrongly implied that Job had hitherto not known God, and that prosperity in this life would follow his sincere conversion. The counsel Eliphaz here gives is good, though, as to Job, it was built upon a false supposition that he was a stranger and enemy to God. Let us beware of slandering our brethren; and if it be our lot to suffer in this manner, let us remember how Job was treated; yea, how Jesus was reviled, that we may be patient. Let us examine whether there may not be some colour for the slander, and walk watchfully, so as to be clear of all appearances of evil.
