Rabbi Yehoshua holds that a bird burnt offering that is slughtered in the place of the bird sin offering and in the way the sin offering is done and with the intent of it being a sin offering, there is no law of meila (misuse of consecrated property). There is a debate between him and Rabbi Eliezer, each bringing arguments and counter-arguments. Rav Ada bar Ahava explains that Rabbi Yehoshua holds that the offering transforms into a sin offering. The gemara asks if the reverse would hold true for a sin offering offered as a burnt offering. Mishnayot in masechet Kinim are brought to question Rav Ada bar Aghava’s understanding of Rabbi Yehoshua.
