4 But you are a tower of refuge to the poor, O Lord, a tower of refuge to the needy in distress. You are a refuge from the storm and a shelter from the heat. For the oppressive acts of ruthless people are like a storm beating against a wall, 5 or like the relentless heat of the desert. But you silence the roar of foreign nations. As the shade of a cloud cools relentless heat, so the boastful songs of ruthless people are stilled.

Matthew Henry's Commentary on Isaiah 25:4-5

Commentary on Isaiah 25:1-5

(Read Isaiah 25:1-5)

However this might show the deliverance of the Jews out of captivity, it looked further, to the praises that should be offered up to God for Christ's victories over our spiritual enemies, and the comforts he has provided for all believers. True faith simply credits the Lord's testimony, and relies on his truth to perform his promises. As God weakens the strong who are proud and secure, so he strengthens the weak that are humble, and stay themselves upon him. God protects his people in all weathers. The Lord shelters those who trust in him from the insolence of oppressors. Their insolence is but the noise of strangers; it is like the heat of the sun scorching in the middle of the day; but where is it when the sun is set? The Lord ever was, and ever will be, the Refuge of distressed believers. Having provided them a shelter, he teaches them to flee unto it.
