Isaiah encourages recently released captives, who doubt the promises that motivated them to leave Babylon, to hope in an offer they should remember. Rebuilding the ancient ruins will not be an easy task but the same promise that delivered them through the wilderness the first time around will deliver them now. Those who had nothing then were given everything so those who have nothing now should expect the same. But you don’t have to be poor to be thirsty as even those who have money to spare often find themselves lacking the peace and comfort riches promise to afford. So we find in this word a promise to which we who have never known captivity in Babylon come running to the Holy One of Israel who offers water, bread, wine and milk that is not restricted to a single nation but is a witness to all people.
