Leviticus 4:29

וְסָמַךְ֙ אֶת־יָד֔וֹ עַ֖ל רֹ֣אשׁ הַֽחַטָּ֑את וְשָׁחַט֙ אֶת־הַ֣חַטָּ֔את בִּמְק֖וֹם הָעֹלָֽה׃

καὶ ἐπιθήσει τὴν χεῖρα ἐπὶ τὴν κεφαλὴν τοῦ ἁμαρτήματος αὐτοῦ, καὶ σφάξουσιν τὴν χίμαιραν τὴν τῆς ἁμαρτίας ἐν τόπῳ οὗ σφάζουσιν τὰ ὁλοκαυτώματα.

Y pondrá su mano sobre la cabeza de la expiación, y la degollará en el lugar del holocausto.

He is to lay his hand on the head of the sin offering and slaughter it at the place of the burnt offering.
