Doubtful orlah: in the land of Israel is prohibited, in Syria is permitted, and outside the land one may go down and purchase [from a non-Israelite] as long as he has not seen him gathering it. A vineyard planted with vegetables [which are kilayim], and they [the vegetables] are sold outside of it: in the land of Israel these are prohibited, and in Syria they are permitted; outside the land one may go down and purchase them as long as he does not gather [them] with [one’s own] hand. New [produce] is prohibited by the Torah in all places. And orlah is a halachah. And kilayim are an enactment of the scribes.
