The great army of Joel 2
In Joel’s prophecy, God’s people are described under the figure of a plague of locusts. [vs. 25] The locust metaphor alludes to the Israelites in the wilderness. After the Exodus, Moses commissioned representatives from each tribe to survey the land that Israel was to inherit. When they returned after 40 days some of the spies gave an evil report, describing the people dwelling in the land as giants, and themselves as grasshoppers. People who have not entered the saints’ promised land are represented in Joel’s prophecy by locusts.
