'Smiter' in the Bible

And it hath come to pass, in that day, The remnant of Israel, And the escaped of the house of Jacob, Do not add any more to lean on its smiter, And have leant on Jehovah, The Holy One of Israel, in truth.

Rejoice not thou, Philistia, all of thee, That broken hath been the rod of thy smiter, For from the root of a serpent cometh out a viper, And its fruit is a flying saraph.

As the smiting of his smiter hath He smitten him? As the slaying of his slain doth He slay?
