Shmuel lists 3 people who can demand land that they are owed – even if it’s valued higher now because its value increased\u00a0– and then need to return the value of the increase to the other. \u00a0A contradictory statement of Shmuel is brought and it is reconciled. \u00a0When one steals and item and it increases in value while in his possession, the increase goes to him and even to those who he sells it to or to his inheritors. \u00a0Rava asks a question based on this regarding a non Jew. \u00a0Cases are brought where some sort of change happens to the item and the gemara determines whether this is a significant change that would enable the robber to acquire the item or not. \u00a0Based on the mishna, the gemara concludes that if one steals oxen and uses them to work his field and then returns them as they were when he stole them, he is not obligated to compensate the owner for the use of the animal as he fulfilled his obligation to return them. \u00a0However in an exceptional case where someone is consistently doing this and abusing the system, he would be obligated.<\/p>\n
