LXX Num 19:18

καὶ λήμψεται ὕσσωπον καὶ βάψει εἰς τὸ ὕδωρ ἀνὴρ καθαρός, καὶ περιρανεῖ ρανεῖ ἐπὶ τὸν οἶκον καὶ ἐπὶ τὰ σκεύη καὶ ἐπὶ τὰς ψυχάς, ὅσαι ἐὰν ὦσιν ἐκεῖ, καὶ ἐπὶ τὸν ἡμμένον τοῦ ὀστέου τοῦ ἀνθρωπίνου ἢ τοῦ τραυματίου ἢ τοῦ τεθνηκότος ἢ τοῦ μνήματος·

Then a man who is ceremonially clean is to take some hyssop, dip it in the water, and sprinkle the tent, all the furnishings, and the people who were there. He is also to sprinkle the one who touched a bone, a grave, or a person who has died or been slain.
