Psalms 105:35

"And did eat up all the grass in their land, and devoured the fruit of the ground" [Psalm 105:35]. Even grass is fruit, as Scripture is wont to speak, which calls even the ripe grain grass; but it wished these two things to harmonize in number with the two which it had spoken of before, that is, the locust and the caterpillar. But the whole of this does belong to the variety of speech, which is a remedy for weariness, not to any difference of senses.

And did eat up all the herbs in their land,.... As these creatures usually do, unless restrained, Exo 10:5. And devoured the fruit of their ground; which the hail left, Exo 10:15.

God did not bring the same plague twice, but, when there was occasion for another, it was still a new one; for he has many arrows in his quiver. Locusts and caterpillars are God's armies; and, how weak soever they are singly, he can raise such numbers of them as to make them formidable, Joel i.

Or, rather, the "darkness" here is figurative (Jer 13:16), the literal plague of darkness (Ex 10:22, 23) being only alluded to as the symbol of God's wrath which overhung Egypt as a dark cloud during all the plagues. Hence, it is placed first, out of the historical order. Thus, "They rebelled not (that is, no longer) against His word," refers to the Egyptians.

Did eat up all the herbs. The locusts had devoured every green herb and every blade of grass; and had it not been for the reeds, on which our cattle entirely subsisted while we skirted the banks of the river, the journey must have been discontinued, at least in the line that had been proposed. The larvae, as generally is the case in this class of nature, are much more voracious than the perfect insect; nothing that is green seems to come amiss to them. The traces of their route over the country are very obvious for many weeks after they have passed it, the surface appearing as if swept by a broom, or as if a harrow had been drawn over it. John Barrow, 1764-1849.
