18:1-8 Care is taken that the priests entangle not themselves with the affairs of this life, nor enrich themselves with the wealth of this world; they have better things to mind. Care is likewise taken that they want not the comforts and conveniences of this life. The people must provide for them. He that has the benefit of solemn religious assemblies, ought to give help for the comfortable support of those that minister in such assemblies.And this shall be the priest's due from the people, from them that offer sacrifice,.... Not from the priests, as Jarchi observes, but from those that bring the sacrifices to the priests, particularly the peace offerings:

whether it be ox or sheep; the one of the herd, the other of the flock, creatures used in sacrifice, and takes in goats and the kids of them, rams and lambs:

and they shall give unto the priest the shoulder, and the two cheeks, and the maw; the first of these designs the upper part of the arm that joins to the neck and back, and the next the two cheeks with the tongue, as both Jarchi and Aben Ezra observe, and indeed the whole head is meant; the maw, which the Septuagint interpreters call and other writers is, according to the philosopher (p), the fourth and last ventricle or stomach, and which he thus describes;"after the echinus or rough tripe is that which is called the maw, which is in size larger than the echinus, and in form longer, and has many large and smooth folds;''and , the maw of an ox, and the belly of a swine, are reckoned by the poet (q) as delicious food.
