When they were filled, he said to his disciples, "Gather up the broken pieces which are left over, that nothing be lost."

 Their minds were still on the feeding of the crowd and inevitably that turned their thoughts to the manna in the wilderness. They could hardly help connecting the two things. The manna had always been regarded as the bread of God ( Psalms 78:24; Exodus 16:15); and there was a strong rabbinic belief that when the Messiah came he would again give the manna. The giving of the manna was held to be the supreme work in the life of Moses and the Messiah was bound to surpass it. "As was the first redeemer so was the final redeemer; as the first redeemer caused the manna to fall from heaven, even so shall the second redeemer cause the manna to fall." "Ye shall not find the manna in this age, but ye shall find it in the age that is to come." "For whom has the manna been prepared? For the righteous in the age that is coming. Everyone who believes is worthy and eateth of it." It was the belief that a pot of the manna had been hidden in the ark in the first temple, and that, when the temple was destroyed, Jeremiah had hidden it away and would produce it again when the Messiah came. In other words, the Jews were challenging Jesus to produce bread from God in order to substantiate his claims. They did not regard the bread which had fed the five thousand as bread from God; it had begun in earthly loaves and issued in earthly loaves. The manna, they held, was a different thing and a real test.
