'Ceremonially' in the Bible

These searched [for their names] among those registered in the genealogies, but they were not found; so they were excluded from the priesthood as [ceremonially] unclean.

When the builders established the Lord's temple, the priests, ceremonially attired and with their clarions, and the Levites (the sons of Asaph) with their cymbals, stood to praise the Lord according to the instructions left by King David of Israel.

All of the priests and Levites were ceremonially clean, because they had purified themselves. They killed the Passover lamb for themselves, their priestly brothers, and all the exiles.
