Amsal 26:27

26:27 The one who digs a pit ¹  will fall into it;

the one who rolls a stone – it will come back on him.

Amsal 28:10

28:10 The one who leads the upright astray in an evil way

will himself fall into his own pit, ² 

but the blameless will inherit what is good. ³ 

[26:27]  ¹ sn The verse is teaching talionic justice (“an eye for an eye,” etc.), and so the activities described should be interpreted as evil in their intent. “Digging a pit” would mean laying a trap for someone (the figure of speech would be a metonymy of cause for the effect of ruining someone, if an actual pit is being dug; the figure would be hypocatastasis if digging a pit is being compared to laying a trap, but no pit is being dug). Likewise, “rolling a stone” on someone means to destroy that individual.

[28:10]  ² 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.

[28:10]  ³ 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).
