Proverbs 26:17-19

Amplified Bible

¹⁷ 
Like one who grabs a dog by the ears [and is likely to be bitten]
Is he who, passing by, stops to meddle with a dispute that is none of his business.
¹⁸ 
Like a madman who throws
Firebrands, arrows, and death,
¹⁹ 
So is the man who deceives his neighbor (acquaintance, friend)
And then says, “Was I not joking?”^(A)
