3:11 And I will rebuke the {l} devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast her fruit before the time in the field, saith the LORD of hosts.
(l) Meaning the caterpillar, and whatever destroys corn and fruits.
3:11 The devourer - All kind of devourers, the locusts, the canker - worm, and the caterpillar, which though they are in incredible multitudes, yet a rebuke from God will check them all at once, as if they were but one. For your sakes - For your good. Your vine - Your vine shall carry their fruit 'till they are fully ripe.
3:7-12 The men of that generation turned away from God, they had not kept his ordinances. God gives them a gracious call. But they said, Wherein shall we return? God notices what returns our hearts make to the calls of his word. It shows great perverseness in sin, when men make afflictions excuses for sin, which are sent to part between them and their sins. Here is an earnest exhortation to reform. God must be served in the first place; and the interest of our souls ought to be preferred before that of our bodies. Let them trust God to provide for their comfort. God has blessings ready for us, but through the weakness of our faith and the narrowness of our desires, we have not room to receive them. He who makes trial will find nothing is lost by honouring the Lord with his substance.
