As a mad man who casteth firebrands,
Arrows, and death,
So is the man that deceiveth his neighbor,
And saith, "Am not I in sport?"
-- Proverbs 26:18-19 (King James Version)
A man who deceives another
and then says, 'It was only a joke',
is like a madman shooting at random
his deadly darts and arrows.
-- Proverbs 26:19, 18 (New English Bible)
