Leviticus 15:4

“Every bed whereon he lieth that hath the issue is unclean, etc.] Which he constantly makes use of; so the Targum of Jonathan, which is peculiar to him, and appointed and appropriated for him to lie upon. Jarchi says, every bed that is fit to lie upon, thou is appropriated to another service; but, he adds meaning is, which he shall lie upon (or continue to lie upon); for it is not said, which he hath laid upon, but which he lieth upon, and is used by him continually; according to the Misnah f521, a man that has an issue defiles a bed five ways, so as to defile a man, and to defile garments; standing, sitting, lying, hanging, and leaning: and everything whereon he sitteth shall be unclean;…”

“thing: Heb. vessel be unclean: Co1 15:33; Eph 5:11; Tit 1:15 Leviticus 15:5”

“Every bed upon which he lay, and everything upon which he sat, was defiled in consequence; also every one who touched his bed ( Lev 15:5), or sat upon it ( Lev 15:6), or touched his flesh, i.e., his body ( Lev 15:7), was unclean, and had to bathe himself and wash his clothes in consequence. Leviticus 15:9”
