God provided manha day after day for 40 years to the Israelites
They could not take more than a day's portion - otherwise it would rot
Manha means "it is what it is"
It was to teach them that man does not live on bread alone but every word that comes from the mouth of the Lord - Deuteronomy 8:2-3
It is NOT inapproprate to ask God to provide for our needs
He is YHWH - jireh - the Lord will provide
God delights in our dependence on Him as the source of our provision
We often do not have because we have not asked - James 4:2
