Psalms 78:43-51

Verse 44

Turned their rivers into blood - See on Exo 7:20 (note).
Verse 45

He sent - flies - and frogs - See on Exo 8:6 (note), and Exo 8:24 (note).
Verse 46

The caterpillar and - the locust - See on Exo 10:13 (note).
Verse 47

He destroyed their vines with hail - Though the vine was never plentiful in Egypt, yet they have some; and the wine made in that country is among the most delicious. The leaf of the vine is often used by the Egyptians of the present day for wrapping up their mince-meat, which they lay leaf upon leaf, season it after their fashion, and so cook it, making it a most exquisite sort of food, according to Mr. Maillet.

And their sycamore-trees - This tree was very useful to the ancient Egyptians, as all their coffins are made of this wood; and to the modern, as their barques are made of it. Besides, it produces a kind of fig, on which the common people in general live; and Mr. Norden observes that "they think themselves well regaled when they have a piece of bread, a couple of sycamore figs, and a pitcher of water from the Nile." The loss therefore of their vines and sycamore-trees must have been very distressing to the Egyptians.
Verse 48

He gave up their cattle - See on Exo 9:23 (note).
Verse 49

By sending evil angels - This is the first mention we have of evil angels. There is no mention of them in the account we have of the plagues of Egypt in the Book of Exodus, and what they were we cannot tell: but by what the psalmist says here of their operations, they were the sorest plague that God had sent; they were marks or the fierceness of his anger, wrath, indignation, and trouble. Some think the destroying angel that slew all the first-born is what is here intended; but this is distinctly mentioned in Psa 78:61. An angel or messenger may be either animate or inanimate; a disembodied spirit or human being; any thing or being that is an instrument sent of God for the punishment or support of mankind.
