Leviticus 15:2-10

²Speak ye to the sons of Israel, and say ye to them, A man that suffereth the running out of seed, shall be unclean;

³and then he shall be deemed to be subject to this vice, when by all moments foul humour, either moisture, cleaveth to his flesh, and groweth altogether.

⁴Each bed in which he sleepeth shall be unclean, and wherever he sitteth.

⁵If any man toucheth his bed, he shall wash his clothes, and he shall be washed in water, and shall be unclean till to eventide.

⁶If a man sitteth where he sat, also that man shall wash his clothes, and he shall be washed in water, and shall be unclean till to eventide.

⁷He that toucheth his flesh, shall wash his clothes, and he shall be washed in water, and shall be unclean till to eventide.

⁸If such a man casteth out spittle upon him that is clean, he shall wash his clothes, and he shall be washed in water, and shall be unclean till to eventide.

⁹The saddle on which he sitteth, shall be unclean; and each man that toucheth whatever thing is under him that suffereth the flowing out of seed, shall be defouled, till to eventide.

¹⁰He that beareth any of these things, shall wash his clothes, and he shall be washed in water, and shall be unclean till to eventide.
