Why did Elijah employ two invocations, saying twice over, "Hear me! hear
me!" (1 Kings xviii. 37.) Elijah first prayed before God, "O Lord, King
of the universe, hear me!" that He might send fire down from heaven and
consume all that was upon the altar; and again he prayed, "Hear me!"
that they might not imagine that the result was a matter of sorcery; for
it is said, "Thou hast turned their heart back again."
