Proverbs 4:19

The way of the wicked is as darkness: they know not at what they stumble.

The way of the wicked is as darkness; they know not at what they stumble - (.) They know not on what peril they may stumble and fall finally. They are in perpetual danger, and know it not, because they are in darkness (; ; cf. as to the godly, "Thou sheet not stumble"). The converse of holds good of them, The path of the unjust is one becoming darker and darker, until it ends in the blackness of darkness forever. They seem (to themselves) clear-sighted and wise; yet they are in the gross darkness of ignorance, error, and sin; and they are in continual danger of being dashed down to outer and everlasting darkness.
