Matthew Poole and continuators on Leviticus 15:18

18 The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even.

Or, The man, to wit, that had such an issue, which is plainly to be understood out of the whole context. For though in some special cases relating to the Worship of God, men were to forbear the use of the marriage-bed, as Exod. 19. 15. and 1 Sam. 21. 4. yet to affirm that the use of it in other cases did generally defile the persons and made them unclean till even is contrary to the whole current of Scripture, which affirm, the marriage-bed to be undefiled, Heb. 13. 4. to the practise of the Jews, which is a good comment upon their own laws, and to the light of nature and reason.
