Proverbs 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.

Es 7:10; Ps 7:15,16; Ps 9:15; Ps 10:2; Ps 57:6; Pr 28:10; Ec 10:8

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.
