The children of Israel spoke against God and Moses, questioning why Moses had brought them into the wilderness to die, and complaining that they had no food or water.
Here is what the Lord did,
“So the LORD sent fiery serpents among the people, and they bit the people; and many of the people of Israel died” (Numbers 21:6).
Israel believed they would die in the wilderness, not believing that the Lord could provide for them or bring them to their own land, so He let their expectations be fulfilled, even sending deadly snakes among them to take their lives!
We need to be careful what we say about our God and the things that He has provided for us.
