Yerushalmi Avodah Zarah 3:10 ירושלמי עבודה זרה ג׳:י׳

MISHNAH: What is an Ashera²⁴⁹Where one has no information to place it in one of the categories of Mishnah 11. Babli 48a.? Any under which is an idol. Rebbi Simeon says, any which is worshipped. It happened in Sidon that they were worshipping one and there was a mound under it. Rebbi Joshua²⁵⁰This is a copyist’s error as shown in the Halakhah. One has to read with all other Mishnah source: R. Simeon. said to them, investigate the mound! They investigated it and found a figure in it. He told them, since they worship the figure we may permit the tree to them²⁵¹The rules of Mishnaiot 13–16 do not apply to this tree.

HALAKHAH: What is an Ashera? Rav Ḥisda said, They disagree in the indeterminate case²⁴⁹Where one has no information to place it in one of the categories of Mishnah 11. Babli 48a.. Where do we hold? If it is certain that they worship both idol and tree, everybody agrees that it is forbidden. But if it is certain that they worship the idol and do not worship the tree, everybody agrees that it is permitted. But where do we hold? If it is indeterminate. Rebbi Simeon says, normally they worship both idol and tree; but the rabbis say, normally they worship the idol but do not worship the tree. And it is difficult. Rebbi Simeon disagrees with the Sages and acts in their sense²⁵²Since in the interpretation of the Halakhah, R. Simeon should have forbidden both tree and idol. But there is nothing to wonder at since R. Simeon insists that practice follow the majority rule against his own opinion, Seviˋit 9:1, Notes 35–36.!
