'Scorpions' in the Bible

and now, my father laid on you a heavy yoke, and I -- I add unto your yoke; my father chastised you with whips, and I -- with scorpions.'

and speaketh unto them according to the counsel of the lads, saying, 'My father made your yoke heavy, and I -- I add unto it; my father chastised you with whips, and I -- with scorpions.'
