“the Levitical priests.” The Masoretic Hebrew text reads, “the priests the Levites,” and this phrase is correct since every priest was also a Levite, but it can be confusing so many versions and commentaries read “Levitical priests,” as does the REV. We know this is speaking of priests and not just Levites because Zadok was a priest so his descendants are priests. [For more on the Levitical priests, see commentary on 2 Chron. 30:27].
“a young bull for a sin offering.” The exact reason for the sacrifices and offerings in the Millennial Temple are not known but there are some likely reasons for them (see commentary on Ezek. 42:13).
