Now that he had their attention, Joel told the people to stop looking around at the locusts and to start looking ahead to the fulfillment of what the locust plague symbolized: the invasion of a fierce army from the north (v. 20). Unless Joel had some other attack in mind, about which we know nothing, he was probably referring to the Assyrian invasion, during the reign of King Hezekiah, which took place in 701 BC (Isa. 36—37). God allowed the Assyrians to ravage the land, but He miraculously delivered Jerusalem from being taken captive. The prophet gave the people three timely instructions.
“Blow the trumphet!” (vv. 1–11). This was real war, so Joel commanded the watchmen to blow their trumpets and warn the people. The Jews used trumpets to call assemblies, announce special events, mark religious festivals, and warn the people that war had been declared (Num. 10; Jer. 4:5; 6:1; Hos. 5:8). In this case, they blew the trumpet to announce war and to call a fast (Joel 2:15). Their weapons against the invading enemy would be repentance and prayer; the Lord would fight for them.
Twice in this passage, Joel tells us that invasion is “the day of the Lord” (vv. 1, 11), meaning a very special period that God had planned and would direct. “The Lord thunders at the head of his army” (v. 11 niv). It was God who brought the locusts of the land and God would allow the Assyrians to invade the land (Isa. 7:17–25; 8:7). He would permit them to ravage Judah just as the locusts had done, only the Assyrians would also abuse and kill people. “Woe to Assyria, the rod of My anger and the staff in whose hand is My indignation. I will send him against an ungodly nation … to seize the spoil, to take the prey, and to tread them down like the mire of the streets” (Isa. 10:5–6 nkjv).
In his vivid account of the invading army, Joel sees them coming in great hordes, “like dawn spreading across the mountains” (Joel 2: niv). Once again, he uses the locusts to describe the soldiers. Just as the locusts had destroyed everything edible before them, so the army would use a “scorched earth policy” and devastate the towns and the land (Isa. 36:10; 37:11–13, 18). The locusts looked like miniature horses, but the Assyrians would ride real horses and conquer the land.
The prophet makes it clear that the Lord will be in charge of this invasion; this is His army fulfilling His word (Joel 2:11). God can use even heathen nations to accomplish His purposes on this earth (Isa. 10:5–7; Jer. 25:9). The awesome cosmic disturbances described in Joel 2: are Joel’s way of announcing that the Lord is in charge, for these signs accompany “the day of the Lord” (3:15; see Zeph. 1:14).
“Rend your hearts!” (vv. 12–17). Once again, Joel called for a solemn assembly where God’s people would repent of their sins and seek the Lord’s help. The nation didn’t know when this invasion would occur, so the important thing was for them to turn to the Lord now. But they must be sincere. It’s easy to participate in a religious ceremony, tear your garments, and lament, but quite something else to humbly confess your sins and bring to God a repentant heart (Matt. 15:8–9). “The sacrifices of God are a broken spirit, a broken and a contrite heart—these, O God, You will not despise” (Ps. 51: nkjv).
The one thing that encourages us to repent and return to the Lord is the character of God. Knowing that He is indeed “gracious and compassionate, slow to anger and abounding in love” (Joel 2: niv) ought to motivate us to seek His face. This description of the attributes of God goes back to Moses’ meeting with the Lord on Mount Sinai, when he interceded for the sinful nation of Israel (Ex. 34:6–7). You find echoes of it in Numbers 14: (another scene of Moses’ intercession); Nehemiah 9:17; Psalms 86:15, 103:8, and 145:8; and Jonah 4:2. Such a gracious God would “turn and have pity” (Joel 2: niv). Note that Joel’s concern was that the people would once again have offerings to bring to the Lord, not just food on their tables.
But all the people must assemble and then turn to the Lord (vv. 15–17). This includes elders and children, nursing babies and priests, and even the newlyweds who were not supposed to be disturbed during their first year of marriage, not even because of war (Deut. 24:5). The prophet even gave them a prayer to use (Joel 2:17) that presents two reasons why God should deliver them: (1) Israel’s covenant privileges as God’s heritage and (2) the glory of God’s name before the other nations. Moses used these same arguments when he pled for the people (Ex. 32:11–13; 33:12–23).
The Jews are indeed God’s special treasure and heritage (Ex. 15:17; 19:5–6; Ps. 94:5; Jer. 2:7; 12:7–9). To Israel, He gave His laws, His covenants, the temple and priesthood, a special land, and the promise that they would bless the whole world (Gen. 12:1–3; Rom. 9:1–5). From Israel came the written Word of God and the gift of the Savior (John 4:22).
Israel was called to bear witness to the other nations that their God was the only true God. How could God be glorified if His people were destroyed and the pagans could gleefully ask, “Where is their God?” (See Ps. 79:10; 115:2; also Mic. 7:10.) The nation had to choose between revival (getting right with God) or reproach (robbing God of glory).
“Believe His promises!” (vv. 18–27). Joel now looks beyond the invasion to the time when God would heal His land and restore His blessings to His people. Just as He blew the locusts into the depths of the Dead Sea and the Mediterranean Sea (eastern and western seas), so He could drive the invading army out of the land. In one night, God killed 185,000 Assyrian soldiers, and Sennacherib went home a defeated king (Isa. 37:36–38). The corpses must have created quite a stench before they were buried.
Some Bible scholars believe that Psalm 126 grew out of this event, for it describes a sudden and surprising deliverance that startled the nation. (Judah’s return from Babylonian captivity was neither sudden or surprising.) “The Lord hath done great things for us; whereof we are glad” (v.3) is echoed in Joel 2:21: “Be glad and rejoice; for the Lord will do great things.” Both Joel 2:23–27 and Psalm 126:5–6 describe the restoration of the ravaged earth and the return of the harvests. This fulfilled what Isaiah promised to King Hezekiah (Isa. 37:30).
Without the former rain (March-April) and the latter rain (October-November), the land could not bear its crops; and one way God disciplined His people was to shut off the rain (Deut. 11:13–17). But the Lord promised to give such bumper crops that the harvest would more than compensate for all the people lost during the locust plague and the drought. “I will repay you for the years the locusts have eaten” (Joel 2: niv) is a word of promise to all who return to the Lord with sincere and broken hearts.
“You cannot have back your time,” said Charles Spurgeon, “but there is a strange and wonderful way in which God can give back to you the wasted blessings, the unripened fruits of years over which you mourned. … It is a pity that they should have been locust-eaten by your folly and negligence; but if they have been so, be not hopeless concerning them.”
And why will God do this for His deserving people? So that they will praise His name and never again be shamed before the heathen. “Then you will know that I am in Israel, that I am the Lord your God, and that there is no other; never again will my people be shamed” (v. 27 niv).
As never before, our lands today need healing. They are polluted by the shedding of innocent blood and the exploiting of both resources and people. We can claim God’s promise in 2 Chronicles 7: because we are “His people.”
