“When you beat down the fruit of your olive trees, do not go over them again; that shall go to the stranger, the fatherless, and the widow.” DEUTERONOMY 24:20 (The Israel Bible™)
Just as grain must be left in the fields for the poor during the time of the harvest, so too fruit must be left on the trees. In describing the process of removing the fruit from the olive tree, the verse says “when you beat down the fruit of your olive trees.” In ancient times, olive trees were harvested by beating the branches with a stick, causing the olives to fall to the ground. According to Jewish tradition, this command hints to the blessing of abundance in the Land of Israel. There will be so much produce that the farmers will only need to harvest what falls off with the beating of the tree branches; they will not even need to bother climbing a ladder to reach the fruit at the top of the tree.
