The names Ben Ish Hai, Me-Kabtziel, Rav Pe'alim and Ben Yehoyada derive from 2 Samuel 23:20. He chose these names because he claimed to have been a reincarnation of Benayahu ben Yehoyada (described as Ben Ish Hayil, the son of a valiant man); the man in whose merit, it is said, both the first and second Holy Temples stood.
