'Concerneth' in the Bible

This is that which concerneth the Levites: from twenty-five years old and upward shall he come to labour in the work of the service of the tent of meeting.

But thou and thy sons with thee shall attend to your priesthood for all that concerneth the altar, and for that which is inside the veil; and ye shall perform the service: I give you your priesthood as a service of gift, and the stranger that cometh near shall be put to death.
