It would have been a different story if the Israelites had come to God for their need of bread.

...............But they turned away from Him, murmuring and complaining:
.....they had been deceived,
.....they had been lead away from Egypt,
a land of peace and plenty,
.....they are now trapped in this terrible wilderness,
.....they all were going to die.

.................God heard their unbelief;
........................but it didn't make Him deny Himself.
