But when he does himself fully understand them he must be both busy and bold to preach them for the good of others. We must not conceal the words of the Holy One (Job vi. 10), for that is burying a talent which was given us to trade with.

He is not sent to the Chaldeans to reprove them for their sins, but to the house of Israel to reprove them for theirs; for the father corrects his own child if he do amiss, not the child of a stranger.
