Matthew Poole and continuators on Joel 1:7

7 He hath laid my vine waste , and barked my fig tree: he hath made it clean bare , and cast it away , the branches thereof are made white.

That Nation of locusts verse 6. both literally and mistically understood.

Made it a desolation, i. e. most desolate, which is more particularly declared in what followeth.

Peel'd off the bark, which is certain destruction to the Tree.

Eat of all the rind, and green bark, and left the body of both Vine and Fig-tree bare and stript.

As vermin cast out of their mouth, the chewings of what they spoil, so here,

all the branches of both Vine and Fig-tree are by these devouring vermin made white, all their green being eaten off; so miserably desolate will the enemy signified by these locusts, make Iudah, Gods Vine.

Marginal references: Heb. laid my fig-tree for a barking.
