Leviticus 23:22
20 and the priest is to wave them—the two lambs—along with the bread of the firstfruits, as a wave offering before the Lord; they will be holy to the Lord for the priest. 21 “‘On this very day you must proclaim an assembly; it is to be a holy assembly for you. You must not do any regular work. This is a perpetual statute in all the places where you live throughout your generations. 22 When you gather in the harvest of your land, you must not completely harvest the corner of your field, and you must not gather up the gleanings of your harvest. You must leave them for the poor and the resident foreigner. I am the Lord your God.’” 23 The Lord spoke to Moses: 24 “Tell the Israelites, ‘In the seventh month, on the first day of the month, you must have a complete rest, a memorial announced by loud horn blasts, a holy assembly.
Obadiah 1:5
3 Your presumptuous heart has deceived you—you who reside in the safety of the rocky cliffs, whose home is high in the mountains. You think to yourself, ‘No one can bring me down to the ground!’ 4 Even if you were to soar high like an eagle, even if you were to make your nest among the stars, I can bring you down even from there!” says the Lord. 5 “If thieves came to rob you during the night, they would steal only as much as they wanted. If grape pickers came to harvest your vineyards, they would leave some behind for the poor. But you will be totally destroyed! 6 How the people of Esau will be thoroughly plundered! Their hidden valuables will be ransacked! 7 All your allies will force you from your homeland! Your treaty partners will deceive you and overpower you. Your trusted friends will set an ambush for you that will take you by surprise!
Notes and References
"... The harvesting itself was a major task that involved the entire community. The men would chop the grain with sickles, cheap ones made of flint, or bronze and iron ones, common only in later days. A piece of flint might be set in the jawbone of an animal, or in a curved piece of wood. (This might explain Samson’s slaughter of the Philistines using the “jawbone of an ass.”) The harvesters would gather their grain into bundles, or sheaves, as Joseph mentioned in describing his dream (Genesis 37:7). The harvesters would bind and then tie these onto the donkey’s back or the camel’s packsaddle for transport to the threshing floor. The harvesters deliberately left grain in the corners of the fi eld and scattered some as they collected the sheaves so that the gleaners could follow along and pick up the leftovers. This custom was part of Mosaic law, for the care of the poor (Leviticus 23:22) ..."
