Peah 3:4-5
Peah 3:4
Peah must be taken for onions that are left in the ground to sprout since they are edible; Rabbi Yossi says they are exempt. When it comes to beds of onions planted between other vegetables, Rabbi Yossi says one must give peah from each bed; the Sages say that one takes peah from one bed for all of them.
Peah 3:5
If two brothers inherit a field and divide it between them, they each give their own peah. If they reunite as joint owners, they give one peah between them. If two people jointly purchase a fruit tree, they give one peah. If one purchases the north side of the tree and the other purchases the south side, then each would give his own peah. If a person sells his trees but not the land they occupy (meaning that the purchaser must uproot the trees and replant them elsewhere), the buyer must take peah for each tree individually. Rabbi Yehuda says this is when the seller didn’t keep any trees for himself but if he did, then the seller gives peah for all the trees.
