Peter Pett's Commentary on the Bible
Joel 2 - Introduction
The Grounds For Seeing Chapter 1 As Referring To Real Locusts And Chapter 2 As Referring To An Invading Army.
Clearly the arguments above support the first part of this position, and the second part is based on the kind of language used in chapter 2. This would be a fairly strong case if all that was in mind was a visit by flying locusts, but descriptions such as Dr Thomson's (see above) of the creeping army of young wingless locusts helps to vividly explain that language. Indeed as we shall see, it brings chapter 2 alive. On the other hand, once the metaphorical idea of an army is removed, the remainder of the language clearly refers to the activities of insects as witnessed by Joel himself and vividly portrayed.
The Grounds For Seeing Both Chapter s As Referring To Human Armies.
This view demands a leap of the imagination from what is presented in chapter 1 to the idea of human armies, and is usually held by those who interpret Joel in accordance with their own pre-conceived notions. Apart from the use of the word ‘nation', which can be explained otherwise (compare its use in Zephaniah 2:14 where it means different species of animals in their groupings, and the reference to different species of creatures as a ‘people' in Proverbs 30:25), there are really no grounds in chapter 1 for considering that it speaks of a human army, and it is noteworthy that the devastations described all adequately apply to insects like locusts, while nothing of what we would see as characteristic of humans (killing, rape, use of the sword, taking captives, etc.), is found anywhere in the narrative (of either chapter 1 or chapter 2). Note how all through it is only natural things that are affected, together with the provision of meal and wine for Temple offerings, with not a word said of any other effects. If Joel wanted us to think that he had locusts in mind he has certainly made a good job of it.
