Talmud zu Schemuel I 17:5

HALAKHAH: Rebbi Jonah says, from the top, as you say (1Sam. 17:5): “A brass helmet on his head.” Round bundles, Rebbi Avinah said, from the bottom, as you say (Deut. 32:34): “It is hidden with me.” ¹³⁹With the different meanings of the Hebrew/Aramaic root חרר, this could mean 1) something burned (a charcoal-broiled cake), 2) a round mass, 3) a hole, 4) freedom. Hence, it is necessary to spell out that meaning 2) is meant.חֲרָרָה a wheel. Small sheaves, Rebbi Joḥanan said (Deut. 24:19): “When you will be harvesting the harvest of your field and you forget a sheaf on the field,” just as harvest has no other harvest after it¹⁴⁰On the same field. This would imply that he who cuts part of his field green either for fodder or for Grünkern, is not subject to the law of the forgotten sheaf., so too a sheaf, which has no other sheaf-making after it.
