sn The image of falling into a pit (a figure of speech known as hypocatastasis, involving implied comparison) is meant to say that the evil to which he guides people will ultimately destroy him.

sn This proverb is teaching that those who corrupt others will be destroyed, usually by their own devices, but those who manage to avoid being corrupted will be rewarded. According to this proverb the righteous can be led astray (e.g., 26:27).
