26 Though his hatred cover itself with guile, his wickedness shall be shown openly before the assembly.
27 Whoever digs a pit [for another man's feet] shall fall into it himself, and he who rolls a stone [up a height to do mischief], it will return upon him. (Proverbs 26:26-27). [Amplified Bible].
On retribution (26:26-27)
26-27 Concealed malice will inevitably be made known. Verse 26 is concerned with how and where evil will be exposed; the sage assumes that righteousness will ultimately be victorious. Verse 27 suggests that whatever people sow they reap. It gives two illustrations-digging a pit and rolling a stone. The digging refers to laying a trap for someone, and rolling it on someone. Measure for measure justice is in view-he will fall into his own pit, or the stone will roll on him. For examples consider Haman (Esther 7:10) and Daniel's enemies (Daniel 6:24-28).
