"Then shall he give the rain of thy seed, that thou shalt sow the ground withal; and bread of the increase of the earth, and it shall be fat and plenteous: in that day shall thy cattle feed in large pastures. The oxen likewise and the young asses that ear the ground shall eat clean provender, which hath been winnowed with the shovel and with the fan. And there shall be upon every high mountain, and upon every high hill, rivers and streams of waters in the day of the great slaughter, when the towers fall. Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound."
These verses highlight the blessed nature of the kingdom. Christ's kingdom will bring not only spiritual blessing but also physical blessing. The "effect of righteousness (32:17)" will leave in its wake agricultural abundance. Drought and destructive heat will become a thing of the past. The rain needed to nourish the planted seeds will come at the proper time. The scarcity of pastureland will vanish. Christ's kingdom will be home not only to resurrected saints but also to human flesh and animals in abundance. Not even the necessary food of the cattle and the donkeys will be lacking. Each will eat pure, rich grain which has been harvested and processed.
Rivers refers to a channel or a canal. The picture is that of irrigation for the purposes of farming. Kingdom blessings will bring an abundance of water for irrigation as well as for consumption. Instead of being home to the idolatrous high places, each mountain and hill will be marked by watercourses, irrigation ditches and naturally occurring canals which have been carved out by the abundance of rain. The Lord says that these things will be realized "in the day of the great slaughter, when the towers fall." Such a pronouncement of judgment almost seems contrary to the peaceful scene painted in the text; however, the fall of God's enemies at the return of His Son will bring true peace to the world. To this point, the peace of the world has been shallow and temporary to say the least. Only the presence of Christ's authority can bring true peace. The genuine believer knows this to be true in his soul (John 14:27), and someday it will be true of his environment.
The lights of the heavens will also be affected by the joy of Jesus' physical reign on earth. Moonlight will be amplified to equal that of the sun, and the sun's brightness will be seven times greater than its current condition. It will not be used to scorch men as is seen in the Great Tribulation (Revelation 16:8); but instead, it will be used to bring needed light for growth and wellness. All things will reflect the inexpressible joy of the Lord's worship. Again, God clarifies the context of these prophecies by adding in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound. These promises are millennial. They are reserved for the time when God will bring spiritual life to the Jewish nation through repentant faith in Jesus the Messiah.
...Thus saith the Lord GOD; I will even gather you from the people, and assemble you out of the countries where ye have been scattered, and I will give you the land of Israel. And they shall come thither, and they shall take away all the detestable things thereof and all the abominations thereof from thence. And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh: That they may walk in my statutes, and keep mine ordinances, and do them: and they shall be my people, and I will be their God (Ezekiel 11:17-20).
