Leviticus 11:35

If the carcase of any swarming thing come in contact with an oven, of small cooking stove, the vessel becomes unclean and must be broken.

The Heb word kîraim† probably means a small cooking stove. LXX. translate -pots with feet." The dual form is used either because the vessel consisted of two parts, or because two portions could be prepared in it; somewhat like a modern egg-boiler for two.
