4 For thus the Lord said to me, As a lion or a young lion growls over its prey, and-when a band of shepherds is called out against it- is not terrified by their shouting or daunted at their noise, so the Lord of hosts will come down to fight upon Mount Zion and upon its hill.
Matthew Henry's Commentary on Isaiah 31:4
Commentary on Isaiah 31:1-5
(Read Isaiah 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.
