"You give them something to eat" was Jesus' command to his disciples after they asked him to send the 5,000 men and their families to get provisions. Can you imagine being in their position? It would have been laughable. With a straight face, Jesus was commanding these 12 guys, with essentially nothing, to feed 5,000 men and their families. He knew they couldn't do what he was asking.
But, Jesus never intended them to obey in their own strength or with their own provisions.
He took the five loaves and the two fish, said a blessing, "then he broke the loaves and gave them to the disciples to set before the crowd" (Luke 9:16). He gave what he commanded. He handed them what they needed to do what he asked.
