Leviticus 11:39

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.

41 `And every teeming thing which is teeming on the earth is an abomination, it is not eaten;

42 any thing going on the belly, and any going on four, unto every multiplier of feet, to every teeming thing which is teeming on the earth -- ye do not eat them, for they [are] an abomination;
