Números 4

you shall count them from thirty years old and upward until fifty years old: all who enter in to wait on the service, to do the work in the Tent of Meeting.

De edad de treinta años arriba hasta cincuenta años los contarás; todos los que entran en compañía, para hacer servicio en el tabernáculo del testimonio.

From thirty years old and upward until fifty years old shalt thou number them; all that enter in to perform the service, to do the work in the tabernacle of the congregation.
