Comment: In spite of what God did for them, the Jews could not maintain their trust in Him when they were faced with further dangers or difficulties.  At a stage, they even wanted to return to Egypt.  It was because of their faithlessness that they spent 40 years on the journey instead of 40 days.  It was only Joshua and Caleb and those who were 20 years and below as well as children born in the wilderness that reached the Promised Land. (Exodus 16:1-4; Numbers 14:1-39) To drive home the importance of trusting in JEHOVAH and not being anxious, He used His servant Moses to remind them of how He cared for them during their years in the wilderness. –  (Deuteronomy 8:2-4) These instances were written to teach us that God Almighty is willing and able to care for us if we continue to exercise faith in Him. – Isaiah 49:15, 16.
