Whoso diggeth a pit shall fall therein: and he that rolleth a stone, it will return upon him.

Wesley's Notes

26:27 Rolleth - Up the hill with design to do mischief to some person.

Matthew Henry's Concise Commentary

26:24-26. Always distrust when a man speaks fair unless you know him well. Satan, in his temptations, speaks fair, as he did to Eve; but it is madness to give credit to him. 27. What pains men take to do mischief to others! but it is digging a pit, it is rolling a stone, hard work; and they prepare mischief to themselves. 28. There are two sorts of lies equally detestable. A slandering lie, the mischief of this every body sees. A flattering lie, which secretly works ruin. A wise man will be more afraid of a flatterer than of a slanderer.

Matthew Henry's Whole Bible Commentary

Verse 27

See here, 1. What pains men take to do mischief to others. As they put a force upon themselves by concealing their design with a profession of friendship, so they put themselves to a great deal of labour to bring it about; it is digging a pit, it is rolling a stone, hard work, and yet men will not stick at it to gratify their passion and revenge. 2. What preparation they hereby make of mischief to themselves. Their violent dealing will return upon their own heads; they shall themselves fall into the pit they digged, and the stone they rolled will return upon them, Ps. 7:15, 16; 9:15, 16. The righteous God will take the wise, not only in their own craftiness, but in their own cruelty. It is the plotter's doom. Haman is hanged on a gallows of his own preparing.

-nec lex est justior ulla

Quam necis artifices arte perire sua-

Nor is there any law more just than that

the contrivers of destruction should perish

by their own arts.
