In that day — About that time: when the Lord shall have washed away the filth of Zion, by those dreadful judgments now described. The branch — The Messiah. The earth — The land which for the sins of the people was made barren, upon their return to Christ shall recover its fertility. Under this one mercy he includes all temporal blessings, together with spiritual and eternal. For them — That shall survive all the forementioned calamities.
