Joel 2:19

He afterwards says, God has answered (8) and said to his people, Behold, I will send to you corn, wine, and oil. The Prophet does not here recite what had been done, but, on the contrary, declares, that God in future would be reconciled to them; as though he said, “I have hitherto been a herald of war, and bidden all to prepare themselves for the coming evil: but now I am a messenger to proclaim peace to you; if only you are resolved to turn to God, and to turn unfeignedly, I do now testify to you that God will be propitious to you; and as to your prayers know that they are already heard; that is, know that as soon as they were conceived, they were heard by the Lord.” Hence he says, He has answered; that is “If, moved by my exhortation, ye return with sincerity to God, he will meet you, nay, he has already met you; he waits not until ye have done all that ye ought to do; but when he bids you to come to his temple and to weep, he at the same time wipes off your tears, he removes every cause of sorrow and anxiety.” God, then, has answered; that is, “I am to you a certain and sufficient witness, that your prayers have been already accepted before God, though, as I have before reminded you, ye have not offered them.”

And, at the same time, he speaks of the effect, Behold, I will send to you corn, wine, and oil; and ye shall be satisfied. Here, by the effects, he proves that God would be propitious; for want of food was the first evidence of God’s displeasure, to be followed by the destruction which the Prophet had threatened. What does he say now? God will restore to you abundance of corn, wine, and oil; and he says further, I will not give you to the Gentiles for a reproach that they may rule over you

We now then apprehend the meaning of the Prophet; for he not only promises that God would be placable but also declares that he was already placable; and this he confirms by external tokens; for God would immediately remove the sins of his wrath, and turn them into blessings. Hence he says, ‘He will give you abundance of corn, wine, and oil, so as fully to satisfy you.’ As they had perceived that God was angry with them by the sterility of the land, and also by its produce being consumed by chafers, by locusts, and other animals or insects; so now the Lord would testify his love to them by the abounding fruitfulness of every thing. And then he joins another sentence, I will not give you any more for a reproach to the Gentiles. When he says, “any more,” he intimates that they had been before exposed to reproach; and we indeed know that they were then suffering many evils; but there remained that destruction of which we have heard. God does then here promise, that they should no more be subject to the reproaches of the Gentiles provided they repented; for the Prophet ever speaks conditionally. It now follows —
