Hosea 2:21
And it shall come to pass in that day, I will hear, saith the LORD, I will hear the heavens, and they shall hear the earth; And it shall come to pass in that day, I will hear, saith the LORD, I will hear the heavens, and they shall hear the earth;
In that day, the promise is of God's renewed covenant with His people in the last days. Those who enter that covenant are His commandment-keeping people. The covenant works through a chain of response through creation that restores harmony between heaven and earth: God hears the heavens, the heavens hear the earth, and the earth in turn responds. That response of the earth is provision and restored agricultural abundance — the crops named in the next verse — bringing the flourishing of God's people.
