Leviticus 11:35

Verse 35. 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.
