Targum Yonasan: It means that, if witnessess testify that he has the ox ... in his possession'.

Bava Kama, 75a: It implies that if the Ganav admits to have stolen the article, he is Patur from paying - even if witnesses subsequently arrive in Beis-Din ¹ "Himatzei" - 'be'Eidim'; "Simatzei" - be'Dayanim', to preclude where he implicates himself. ²

Refer to 22:3:1:2.

Rashi and Rashbam: To teach us that if the Ganav still has the animal in his possession (and has not Shechted or sold it), he pays (not four or five times, but) double. ¹

Oznayim la'Torah: Based on the principle 'Shechitah she'Einah Re'uyah Lo Sh'mah Shechitah', non-Kasher animals are not subject to the Din of Arba'ah va'Chamishah for Shechting them, and consequeently, not for selling them either, ¹ whereas there is no reason to preclude them from the Din of Kefel.

Bava Kama, 65a: To teach us that, if the value of the stolen article dropped, the Ganav pays the Keren - as implied by the word "ha'Geneivah" - according to its value when he stole it. ² but Kefel and Arba'ah va'Chamishah according to ts current value.

Yerushalmi Bava Kama, 1:1 #1: "Chayim Shenayim Yeshalem" implies that, if the animal or the the artivle that the Ganav or Gazlan stole dies or breaks, he cannot force the owner to take the Neveilah or the broken pieces as part payment and add the balance but must assess their value and pay accordingly. ³

Yerushalmi Bava Kama, 1:1 #2: "Chayim Shenayim Yeshalem" implies that the Kefel (and the Aarba'ah va'Chamishah) go to the same person as the Keren, and that, consequently, if Reuven deposits his animal with Shimon, the animal is stolen and Shimon swears and is Patur, when the Ganav is found, since he obviously pays the Keren to Reuven, he pays the the Kefel and the Arba'ah va'Chamishah too, to Reuven. ⁴

Bava Kama, 63b: To incorporate things other than animals. ¹

Bava Kama, 64b: The Torah inserts "Shnayim Yeshalem" to teach us that, as opposed to To'en Ta'anas Ganav, the Ganav pays Kefel even without a Shevu'ah. ¹
