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.
