Leviticus 11:37

34 `Of all the food which is eaten, that on which cometh [such] water, is unclean, and all drink which is drunk in any [such] vessel is unclean;

35 and anything on which [any] of their carcase falleth is unclean (oven or double pots), it is broken down, unclean they [are], yea, unclean they are to you.

36 `Only -- a fountain or pit, a collection of water, is clean, but that which is coming against their carcase is unclean;

37 and when [any] of their carcase falleth on any sown seed which is sown -- it [is] clean;

38 and when water is put on the seed, and [any] of its carcase hath fallen on it -- unclean it [is] to you.

39 `And when any of the beasts which are to you for food dieth, he who is coming against its carcase is unclean till the evening;

40 and he who is eating of its carcase doth wash his garments, and hath been unclean till the evening; and he who is lifting up its carcase doth wash his garments, and hath been unclean till the evening.
