"And if his offering is a sacrifice of peace-offerings" (Leviticus 3:1). Rabbi Judah said: Everyone who brings peace-offerings (shelamim) brings peace (shalom) to the world. I have only peace-offerings; from where do I include the thanksgiving-offering? I would include the thanksgiving-offering, since it comes as a peace-offering. From where do I include the burnt-offering? I would include the burnt-offering, since it comes by vow and freewill gift. From where do I include the firstborn, the tithe, and the Passover-offering? I would include the firstborn, the tithe, and the Passover-offering, since they do not come on account of sin. From where do I include the sin-offering and the guilt-offering? Scripture teaches "sacrifice." From where do I include the birds, the meal-offerings, the wine, the frankincense, and the wood? Scripture teaches "his offering." Peace-offerings - thus everyone who brings peace-offerings brings peace to the world.
Whoever Brings a Peace Offering Brings Peace to the World
Yalkut Shimoni on Torah 458:1
