(99) Woe to you, ye obstinate of heart, who work wickedness and eat blood: Whence have ye good things to eat and to drink and to be filled? From all the good things which the Lord the Most High has placed in abundance on the earth; therefore ye shall have no peace.

(7) And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another's flesh, and drink the blood.

(18) But whence could they understand or comprehend these things? We who have rightly understood speak the commandments as the Lord wished; wherefore He circumcised our ears and hearts, that we may comprehend these things. And when he says, 'Thou shalt not eat the eagle, the hawk, the kite, and the crow; he says,' Thou shalt not adhere to or become like those men who know not how to procure for themselves subsistence by toil and sweat, but live by plunder, and lawlessly.' For the eagle indicates robbery, the hawk injustice, and the raven greed. It is also written,' With the innocent man thou wilt be innocent, and with the chosen choice, and with the perverse thou shall pervert.' It is incumbent on us to cleave to the saints, because they that cleave to them shall be sanctified."

And the same law commands "not to muzzle the ox which treadeth out the corn: for the labourer must be reckoned worthy of his food."
