# Should we kill flocks and herds to satisfy them? Should we catch all the fish in the sea to satisfy them?

"We would have to kill entire flocks and herds and catch all the fish in the sea to satisfy them!" 

# all the fish in the sea

The word "all" is an exaggeration to show how impossible it was to provide food for all the people of Israel. 

# to satisfy them

"to satisfy their hunger"
