כָּסּ֣וּ הָרִ֣ים צִלָּ֑הּ וַ֝עֲנָפֶ֗יהָ אַֽרְזֵי־אֵֽל׃
그 그늘이 산들을 가리우고 그 가지는 하나님의 백향목 같으며
Mishnah Sheviit
They may clear away stones until Rosh Hashanah. They may trim, prune and remove [excess parts of the tree] until Rosh Hashanah. Rabbi Joshua says: just as one may trim and remove in the fifth year so too may one perform this work in the sixth year. Rabbi Shimon says: as long as I may legally tend the tree itself, I may remove [excess parts of it].
