The Bird's Crop Full of Robbery and the Honest Grazing Beast

"And he shall remove its crop" -- Rabbi Tanhum bar Hanilai said: This bird flies and soars across the whole world and eats from every side, and it eats from what is stolen and from what is seized by violence. The Holy One, blessed be He, said: Since this crop is full of robbery and violence, let it not be offered upon the altar. But a domestic animal grows up at its owner's feeding-trough and does not eat from every side, neither from robbery nor from violence; therefore one offers all of it. Thus it is said (above, verse 13), "and the priest shall bring the whole and turn it into smoke at the altar." Because this creature robs and seizes, come and see how much pain and how much toil there is until its food passes out of it: from the mouth to the gullet, from the gullet to the stomach, from the stomach to the first chamber, from the first chamber to the second chamber, from the second chamber to the belly, from the belly to the intestines, from the intestines to the thin coil, from the thin coil to the thick coil, from the thick coil to the lower bowel, from the lower bowel to the rectum, and from there outside. Come and see how much pain and how much toil there is until its food passes out of it.
