Exodus 15:22 - Joseph Benson’s Commentary on the Old and New Testaments

They went three days and found no water Here we see that deliverances, however great, do not exempt from future difficulties and trials. Never was a greater deliverance, of a temporal nature, wrought out for any people than that of the Israelites from Pharaoh and from Egypt. It is the most wonderful act of God's almighty power, next to the creation of the world, and its destruction by, and subsequent restoration from the flood, which we read of in the Old Testament: or rather, it is a series of acts, each more wonderful than the other. And yet the very people, thus delivered, find themselves, immediately on their deliverance, with their numerous flocks, and herds, and little ones, in danger of perishing with thirst! And when, after three days of distress on this account, they found water, could not drink of it because it was bitter. But this was for the trial of their faith and patience; and after the wonderful things God had done for them, they were perfectly inexcusable in murmuring against Moses, which was, in effect, murmuring against God. How marvellous was the patience of God with this people!
