Proverbs 30:10-14

Accuse not a servant unto his master, lest he curse thee, and thou be found guilty. There is a generation that curseth their father, and doth not bless their mother. There is a generation that are pure in their own eyes, and yet is not washed from their filthiness. There is a generation, O how lofty are their eyes! and their eyelids are lifted up. There is a generation, whose teeth are as swords, and their jaw teeth as knives, to devour the poor from off the earth, and the needy from among men.

All the several generations here spoken of are to be accounted for the same way. Every unawakened sinner is sleeping in the security of self-confidence, and his eyes have never been opened to see the spots of his own soul. And how then shall he be washed from his filthiness who denieth, because he knoweth not his own uncleanness. How sweet that prayer of David: Cleanse thou me from secret faults. Psalms 19:12. And how becoming that prayer of the leper: Lord! if thou wilt thou canst make me clean. Matthew 8:2. Reader! can you adopt the language of both? If so, surely you are not of the generation Agur speaks of.
