The remnant that is escaped of the house of Judah. — Rather, the survival (survivors) of the house of Judah that are left. (Comp. Isaiah 11:11-16.)
Shall yet again take root. — Literally, shall add root, i.e., shall take firmer root, like a tree after a storm. The figure naturally follows on the language of 2 Kings 19:29. It is thoroughly in the style of Isaiah. (Comp. Isaiah 6:13; Isaiah 27:6.)
