Mishnayos Kiddushin Perek 1 Mishnah 4

במסירה – the owners transfer it to the purchaser by a bit or by its hair.

בהגבהה – but not by taking possession by drawing towards one’s self the object to be acquired

נקנית במשיכה – and even though that it is possible [to be acquired] by lifting, nevertheless, it is acquired by “pulling” (i.e., drawing towards oneself the object to be acquired), because it clutches [the ground], for she becomes strong with her nails by grasping through the ground. And the Halakhic decision is that whether [we are speaking of] a small animal or a large animal, it is acquired by “pulling” and all the more so by lifting up, for “pulling” acquires in a market-stand/alley adjoining an open place to which merchants retire to transact business, which is the corner of the public domain, or in the courtyard of both of them (i.e., the seller and the purchaser). But “pulling” purchases in the public domain or in a courtyard that does not [belong] to them both. And “lifting” acquires in any place. And all that it is customary [to acquire] through “lifting” is not acquired other than through lifting. And Something that is acquired by transferring is not acquired by pulling. And similarly, a thing that is acquired by “pulling” is not acquired by transferring.
