"You shall not wear a garment of sha'atnez"—Deuteronomy 22:11.
It is forbidden to wear a garment woven [or sewn] of wool and linen, as was the practice of ancient pagan priests, and still practiced today [Ed.'s note: in Maimonides' times] amongst Egyptian monks.
"...you shall leave them over"—Leviticus 19:10.
We are commanded to leave over the edge of our grain and fruit crops for the poor and the stranger.
This commandment applies to an individual tree as it does to a field, and only in the Land of Israel.
"Do not remove the corners of your field when you reap the harvest"—Leviticus 23:22.
It is forbidden to harvest an entire field without leaving over the edge for the needy.
