Out of Jerusalem shall go forth a remnant - The Jews shall be so multiplied as not only to fill Jerusalem, but all the adjacent country.

And they that escape out of Mount Zion - Some think that this refers to the going forth of the apostles to the Gentile world, and converting the nations by the preaching of the Gospel.

For out of Jerusalem shall go forth a remnant, and they that escape out of mount Zion: the {x} zeal of the LORD of hosts shall do this.

(x) The love, that God has for his Church will overcome the counsels and enterprises of men.

19:31 Go forth - That handful of Jews who were now gathered together, and shut up in Jerusalem, shall go out of their several habitations, and by my singular blessing increase exceedingly. The zeal - Although when you reflect upon yourselves, and consider either your present fewness, and weakness, or your great unworthiness, this may seem too great a blessing for you to expect; yet God will do it from the zeal which he hath, both for his own name, and for the good of his undeserving people.

19:20-34 All Sennacherib's motions were under the Divine cognizance. God himself undertakes to defend the city; and that person, that place, cannot but be safe, which he undertakes to protect. The invasion of the Assyrians probably had prevented the land from being sown that year. The next is supposed to have been the sabbatical year, but the Lord engaged that the produce of the land should be sufficient for their support during those two years. As the performance of this promise was to be after the destruction of Sennacherib's army, it was a sign to Hezekiah's faith, assuring him of that present deliverance, as an earnest of the Lord's future care of the kingdom of Judah. This the Lord would perform, not for their righteousness, but his own glory. May our hearts be as good ground, that his word may strike root therein, and bring forth fruit in our lives.
