Solomon saith, Proverbs 27:2: Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips. Self-commendation is an ungrateful sound to ingenuous ears; no man thinks another a jot the better for his commending himself, but always hath the worse opinion of him for such boasting; but this text speaketh of a higher approbation, viz. from God. No man is approved of God for his speaking well of himself; the business is, who they are who approve themselves in the work which God hath committed to them; to whom the Lord will say: Well done, good and faithful servants: to whom the apostle refers both himself, and those who magnified themselves, but vilified him.
