“And it will come about in that day, I will answer,” says YHWH, “I will answer the heavens, and they will answer the earth, and the earth will answer the grain, and the new wine, and the oil, and they will answer Jezreel.”
In that day it is God Who will act. It is He Who will commence the process. He will finally give the ‘answer'. He will provide the final solution. His answer will be given to the heavens, so that they may pour rain on the earth, and the heavens will give it to the earth so that it will be responsive to the rain, and the earth will give it to the grain, new wine and oil, so that they will spring forth from the earth, and they will give it to ‘Jezre-el' (‘El sows'), who represents Israel. Israel will be fully blessed and provisioned. So instead of vengeance Jezre-el will signify reception of blessing as provided by God (El sows). His name will speak of God as sowing blessing. And the whole of creation will be involved (compare Romans 8:19-23).
Consider how the grain and the wine and the oil, which they had seen as provided to them by Baal, will now be known to have come from YHWH (compare Hosea 2:6; Hosea 2:8). For now they will ‘know YHWH' and acknowledge Him in all His uniqueness.
