Great(i) 5 Therfore shall ye kepe the holy place and the aulter, that ther fall no more wrath vpon the chyldren of Israel: 6 beholde, I haue taken your brethren the Leuites from amonge the the childreen of Israel, which as a gyft of yours are geuen vnto the Lorde, to do the seruyce of the tabernacle of witnes. 7 Therfore shalt thou and thy sonnes with the take hede vnto your preastes offyce for all thynges that perteyne vnto the aulter, and for all that are within the vayle. And se that ye serue: for I haue geuen your prestes office vnto you as a gyft: and therfore the straunger that commeth nye, must be slayne.
