Now - This verse commences another transition. In the previous verses, the desolation of the land had been described, and the hopelessness of obtaining any terms of favor from Sennacherib, or of binding him to any compact, bad been stated. In this state of things, when inevitable ruin seemed to be coming upon the nation, God said that he would interpose.
Will I rise - To vengeance; or to punish the invading host. The emphasis in this passage should be placed on ‘I,’ indicating that Yahweh would himself do what could not be effected by people.
Now will I be exalted - That is, God would so interpose that it should be manifest that it was his hand that brought deliverance.
