David at the cave of Adullam thus addressed his persecutor Saul
(1 Sam. 24:14): "After whom is the king of Israel come out?
after whom dost thou pursue? after a dead dog, after a flea?" He
thus speaks of himself as the poor, contemptible object of the
monarch's pursuit, a "worthy object truly for an expedition of
the king of Israel with his picked troops!" This insect is in
Eastern language the popular emblem of insignificance. In 1 Sam.
26:20 the LXX. read "come out to seek my life" instead of "to
seek a flea."
