Matthew 15:37

‘And they all ate, and were filled, and they took up what remained over of the broken pieces, seven baskets full.'

And as before all ate and were filled. There is no lack of sufficiency when Jesus feeds men and women with the bread of life. And even what was left over was a sufficiency of divine supply (seven). The word for baskets here refers to non-wicker baskets, and they were regularly, although not always, of a larger size. These ones were probably usually used to hold catches of fish. We are specifically informed in Matthew 16:9 that what was eaten and what was left over symbolised the teaching of Jesus, and therefore of the Kingly Rule of Heaven. Thus the leftovers probably also indicate that there is a surplus to be take out to others, that all who will might be filled.
