The moral of today's first reading (1Kings 17:7-16) is that God will take care of His faithful prophets/priests through others and He will care also for those who generously provide for His prophets/priests in his name.
Noone is too poor to share nor too rich to need to share.
Everyone needs to share with God in providing for those whom He sends.
Faith is the greatest wealth.
As Abraham said to Isaac: Deus providebit.
