They considered it.

The Israelites said to them, "If only we had died by the LORD's hand in Egypt! There we sat around pots of meat and ate all the food we wanted, but you have brought us out into this desert to starve this entire assembly to death." - Exodus 16:3

But the people were thirsty for water there, and they grumbled against Moses. They said, "Why did you bring us up out of Egypt to make us and our children and livestock die of thirst?" - Exodus 16:20

The rabble with them began to crave other food, and again the Israelites starting wailing and said, "If only we had meat to eat! We remember the fish we ate in Egypt at no cost - also the cucumbers, melons, leeks, onions, and garlic. But now we have lost our appetite; we never see anything, but this manna!" - Numbers 11:4-6

All the Israelites grumbled against Moses and Aaron, and the whole assembly said to them, "If only we had died in Egypt! Or in this desert! Why is the LORD bringing us to this land only to let us fall by the sword? Our wives and children will be taken as plunder. Wouldn't it be better for us to go back to Egypt?" And they said to each other, "We should choose a leader and go back to Egypt." - Numbers 14:2-4

They quarreled with Moses and said, "If only we had died when our brothers fell dead before the LORD! Why did you bring the LORD's community into this desert, that we and our livestock should die here? Why did you bring us up out of Egypt to this terrible place? It has no grain or figs, grapevines or pomegranates. And there is no water to drink!" - Numbers 20:3-5
