Fear not, thou worm Jacob, and ye men of Israel; I will help thee, saith the LORD, and thy redeemer, the Holy One of Israel. Fear not, thou worm Jacob - In the rabbinical commentary on the five books of Moses, Yelamedenu, it is asked, Why are the Israelites called a worm? To signify, that as the worm does not smite, that is, gnaw the cedars, but with its mouth, which is very tender, yet it nevertheless destroys the hard wood; so all the strength of the Israelites is in prayer, by which they smite the wicked of this world, though strong like the cedars, to which they are compared, Ezekiel 31:3.
