Charles H. Spurgeon on Psalms 78:46

He gave also their increase unto the caterpillar, and their labour unto the locust. Different sorts of devourers ate up every green herb and tree. What one would not eat another did. What they expected from the natural fertility of the soil, and what they looked for from their own toil, they saw devoured before their eyes by an insatiable multitude against whose depredation no defense could be found. Observe in the text that the Lord did it all —"he sent, " "he gave, ""he destroyed, ""he gave up, "etc.; whatever the second agent may be, the direct hand of the Lord is in every national visitation.
