Amos 7:1

Sovereign Yahweh showed Amos a mass of locusts swarming in the springtime after the first harvest and before the second. The Lord was forming this swarm of locusts. Ideally the very first crops harvested in the spring went to feed the king’s household and animals (cf. 1 Kings 18:5). The crops that the people harvested later in the spring fed their animals and themselves. If anything happened to prevent that second harvesting, the people would have little to eat until the next harvest in the fall. The summer months were very dry and the Israelites had nothing to harvest during that season of the year.

Locusts swarming indicated that they were about to sweep through an area and destroy all the crops. There was no way to prevent this in Amos’ day. Locust invasions were a perennial threat, and they were a method of discipline that God had said He might use if His people proved unfaithful to His covenant with them (Deuteronomy 28:38; Deuteronomy 28:42; cf. Joel 1:1-7; Amos 4:9).
