31:1-5 God will oppose the help sought from workers of iniquity. Sinners may be convicted of folly by plain and self-evident truths, which they cannot deny, but will not believe. There is no escaping the judgments of God; and evil pursues sinners. The Lord of hosts will come down to fight for Mount Zion. The Lion of the tribe of Judah will appear for the defence of his church. And as birds hovering over their young ones to protect them, with such compassion and affection will the Lord of hosts defend Jerusalem. He will so defend it, as to secure its safety.
5. As in the image of "the lion," the point of comparison is the fearless might of Jehovah; so in that of the birds, it is His solicitous affection (De 32:11; Ps 91:4; Mt 23:37).
flying—Rather, "which defend" their young with their wings; "to fly" is a secondary meaning of the Hebrew word [Maurer]. "Hovering over" to protect their young [G. V. Smith].
passing over—as the destroying angel passing over, so as to spare the blood-marked houses of the Israelites on the first passover (Ex 12:13, 23, 27). He passed, or leaped forward [Lowth], to destroy the enemy and to spare His people.
