Proverbs 26:19 Meaning and Commentary

Proverbs 26:19

So [is] the man [that] deceiveth his neighbour
By telling him a lie; or by reporting false things concerning him; or by cheating him in trade and commerce; or by taking his goods privately from him; and, when caught in either of these, and saith, Am not I in sport?
do not be angry, I designed no hurt; it is all in jest, a mere joke: but, had he not been apprehended, it would have been in earnest, as he was. This is only an excuse, and as absurd an one as if a man should set fire to his neighbour's house and barns, or throw arrows at him, or strike him with any instrument of death, as the sword and then say he was only in jest, or pretend madness.

Proverbs 26:19 In-Context

17 As he that lays hold of a dog's tail, so is he that makes himself the champion of another's cause.
18 As those who need correction put forth words to men, and he that first falls in with the proposal will be overthrown;
19 so are all that lay wait for their own friends, and when they are discovered, say, I did it in jest.
20 With much wood fire increases; but where there is not a double-minded man, strife ceases.
21 A hearth for coals, and wood for fire; and railing man for the tumult of strife.
