'Baskets' in the Bible

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

The people ate and were filled. Then the disciples picked up the leftover pieces seven large baskets full.

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."
