TSK · Numbers 18:17

And put his hande vpon the head of his offeryng, and kyll it at the doore of the tabernacle of the congregation: And Aarons sonnes the priestes shal sprinkle the blood vpon the aulter round about.

All the first males that come of thy cattell and of thy sheepe, thou shalt halowe vnto the Lorde thy God: Thou shalt do no worke with the first borne bullocke, nor sheare the first gendred of thy sheepe.
