'Leftover' in the Bible

Then the disciples picked up twelve baskets full of leftover bread and fish.

They ate and were filled. Then they collected seven large baskets of leftover pieces.

When I broke the five loaves for the 5,000, how many baskets did you fill with leftover pieces?" They told him, "Twelve."

"When I broke the seven loaves for the 4,000, how many large baskets did you fill with the leftover pieces?" They told him, "Seven."
