וְכֹל֩ אֲשֶׁ֨ר תִּשְׁכַּ֥ב עָלָ֛יו בְּנִדָּתָ֖הּ יִטְמָ֑א וְכֹ֛ל אֲשֶׁר־תֵּשֵׁ֥ב עָלָ֖יו יִטְמָֽא׃
Targum Jonathan on Leviticus
Whatever such an one shall lie upon during the time of her separation shall be unclean; and whatever such an one sitteth upon during the time of her separation shall be unclean.
