'Bed' in the Bible

"'Every bed whereon he who has the discharge lies shall be unclean; and everything he sits on shall be unclean.

Whoever touches his bed shall wash his clothes, and bathe himself in water, and be unclean until the evening.

Whoever touches her bed shall wash his clothes, and bathe himself in water, and be unclean until the evening.

If it is on the bed, or on anything whereon she sits, when he touches it, he shall be unclean until the evening.

"'If any man lies with her, and her monthly flow is on him, he shall be unclean seven days; and every bed whereon he lies shall be unclean.

Every bed whereon she lies all the days of her discharge shall be to her as the bed of her period: and everything whereon she sits shall be unclean, as the uncleanness of her period.
