Talmud sobre Terumot 9:4

So is the Mishnah: The seeds on the stem of arum¹³⁸This is the reading and interpretation of Maimonides. The other interpretations (R. Isaac Simponti, R. Simson) have to rearrange the sentence except for R. Isaac Simponti’s second explanation, “the seeds of the thorns of arum,” which does not fit reality since arum, an aracea, has no thorns.. Some woman had heave purslain on a block. They fell into a garden and sprouted. The case came before Rebbi Joḥanan who permitted. Rebbi Ḥiyya bar Abba said to him, is this not the Mishnah: “And these may be eaten if their father was heave?” He said to him, Babylonian, when you cleared a potsherd for yourself, you found a pearl! You said, is that not the Mishnah!
