Proverbs 22:21

That I may make thee know the certainty of the words of truth; that I may teach thee, not false, or vain, or uncertain things, as the teachers of the heathen nations do, but the true and infallible oracles of God. That thou mightest answer the words of truth; that being instructed by me, thou mayst be able to give true, and solid, and satisfactory answers. To them that send unto thee, to wit, for thine advice in great and difficult matters. Or, to those that send thee, i.e. that employ the in any business of moment, whereof they expect an account from thee.
