What’s the difference between when they complained the first time about their diet and now? Well, the difference is that a year in their lives has transpired, and during that year God has revealed a great deal about Himself. When they came out of Egypt they didn’t know much about God at all. They were a nation of slaves. But He’d begun to teach them about Himself at Sinai. He taught them that He is a holy God, and that He is a powerful God. They’d seen the miracles. The Israelites knew how He was preserving them as they went through the desert by the manna they ate and the water they drank. A great cloud overshadowed the camp in order to protect them from the hot desert sun in the daytime, and then it turned into a pillar of fire at night to provide both warmth and light. They had perfectly adequate evidence of the power and the grace of God and shouldn’t have been complaining now.
