See Leviticus 2:4. The word rendered "ranges for pots" has been conjectured to mean either an excavated fireplace, fitted to receive a pair of ovens, or a support like a pair of andirons.

Ranges for pots - To understand this, we must observe that the Arabs dig a hole in their tent, about a foot and a half deep; three-fourths of this, says Rauwolff, they lay about with stones, and the fourth part is left open for the purpose of throwing in their fuel. This little temporary building is probably what is here designed by ranges for pots; and this was to be broken down when any unclean thing had fallen upon it. See Harmer, vol. 1., p. 464.

And everything whereupon any part of their carcass falleth shall be unclean,.... Before the Scripture seems to speak of anyone of the reptiles perfect, that falling upon anything should pollute it; but here of any part of them, though ever so small, which should, through any accident, fall and light upon anything, even that would render it unclean and unfit for use:

whether it be oven, or ranges of pots; the one to bake bread in, and the other to boil flesh in, as Aben Ezra observes:

they shall be broken down; and no more made use of for baking and boiling:

for they are unclean, and shall be unclean to you; were made hereby unfit for use, and should not be used: the Jewish writers (x) explain the phrase, "to you", to your necessity, that which they had need of, but now should not use nor receive advantage from; even "to you"; all men, women, and children, as Hiskuni interprets it: all this was ordered to create in them an abhorrence of these creatures, and to make them cautious of eating and touching them, and careful that they come not nigh, or touched, or fell upon anything, since it would give them so much trouble, as well as occasion loss. (x) Maimon. & Bartenora in Misn. Edaiot, c. 7. sect. 8.

Every vessel also became unclean, upon which the body of such an animal fell: such as תּנּוּר, the earthen baking-pot (see Leviticus 2:4), and כּירים, the covered pan or pot. כּיר, a boiling or roasting vessel (1 Samuel 2:14), can only signify, when used in the dual, a vessel consisting of two parts, i.e., a pan or pot with a lid.

And every thing whereupon any part of their carcass falleth shall be unclean; whether it be oven, or ranges for pots, they shall be broken down: for they are unclean and shall be unclean unto you.

11:1-47 What animals were clean and unclean. - These laws seem to have been intended, 1. As a test of the people's obedience, as Adam was forbidden to eat of the tree of knowledge; and to teach them self-denial, and the government of their appetites. 2. To keep the Israelites distinct from other nations. Many also of these forbidden animals were objects of superstition and idolatry to the heathen. 3. The people were taught to make distinctions between the holy and unholy in their companions and intimate connexions. 4. The law forbad, not only the eating of the unclean beasts, but the touching of them. Those who would be kept from any sin, must be careful to avoid all temptations to it, or coming near it. The exceptions are very minute, and all were designed to call forth constant care and exactness in their obedience; and to teach us to obey. Whilst we enjoy our Christian liberty, and are free from such burdensome observances, we must be careful not to abuse our liberty. For the Lord hath redeemed and called his people, that they may be holy, even as he is holy. We must come out, and be separate from the world; we must leave the company of the ungodly, and all needless connexions with those who are dead in sin; we must be zealous of good works devoted followers of God, and companions of his people.
