He will also send you rain for the seed you sow in the ground, and the food that comes from the land will be rich and plentiful. In that day your cattle will graze in broad meadows. The oxen and donkeys that work the soil will eat fodder and mash, spread out with fork and shovel. In the day of great slaughter, when the towers fall, streams of water will flow on every high mountain and every lofty hill. The moon will shine like the sun, and the sunlight will be seven times brighter, like the light of seven full days, when the Lord binds up the bruises of his people and heals the wounds he inflicted.
Isaiah shares the fact that, not only would God hear the cry of His people, but He would also take care of them, Here, the prophet speaks of the Millennial Reign and the fact that the land of Israel will once again be very rich and productive. The "day of great slaughter" refers to the battle where Satan leads the nations against Jerusalem just before the arrival of Jesus to deliver His people (see Revelation 19). The end of this battle will start the Millennial Reign and the "streams of water" refers to the fact that the people will be taught about the things of God by Jesus. The days and nights will be much brighter just because of the presence of Jesus Christ. This is preparation for the new Jerusalem where the glory of the Lord will provide all of its light (see Revelation 21). The bruises and wounds that Isaiah speaks of refers to the suffering of the Jewish people that is growing in our world today. This suffering at the hands of the nations will be ended with the arrival of Jesus and the final battle. So, what about the part that says "he inflicted" the wounds? The suffering that afflicts God's people even today is allowed by God and it has a purpose which is to draw them to Him and His saving grace. We are reminded of the fact that, even for this final battle, it is God that draws the nations against Jerusalem (see Ezekiel 38) so that His glory and power can be displayed to the nations and to His people.
