'Mortal' in the Bible

And Asa calleth unto Jehovah his God, and saith, 'Jehovah! it is nothing with Thee to help, between the mighty and those who have no power; help us, O Jehovah, our God, for on Thee we have leant, and in Thy name we have come against this multitude; O Jehovah, our God thou art; let him not prevail with Thee -- mortal man!
