John Wesley on 2 Kings 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.
