(Devarim 24:20) "When you beat your olive tree, you shall not cut off (lo tefa'er) after you": The early settlers would beat their olive trees and act magnanimously (with what was left on them). "your olive trees": to exclude (from peah) those of gentiles.

"your olive trees": to exclude those of the Temple. "

lo tefa'er": You shall not "lord it" over the poor man — whence they ruled: One who does not allow the poor to pick (the gleanings) or allows one but not another, or helps one of them (to pick) is robbing from the poor. And concerning such as this it is written (Proverbs 22:28) "Do not remove the bounds of yore."

"after you": We are hereby taught that shikchah obtains with an olive tree.

"after you": We are hereby taught that peah obtains with an olive tree.

"to the stranger, to the orphan and to the widow shall it be": It is written here "stranger, orphan," and above (19) "stranger, orphan." Just as there (to render it subject to shikchah) its capacity must be less than two sa'ah, so, here. From here it was ruled: An olive tree which contains two sa'ah and which was forgotten is not subject to shikchah. An olive tree standing between (any two of) three rows (of olive trees) separated by a plot of two malbenim (six hand-breadths) from one another is not shikchah.
