KJV:

20 Neither shall they shave their heads, nor suffer their locks to grow long; they shall only poll their heads.
21 Neither shall any priest drink wine, when they enter into the inner court.
22 Neither shall they take for their wives a widow, nor her that is put away: but they shall take maidens of the seed of the house of Israel, or a widow that had a priest before.

NASB:

20 "Also they shall not shave their heads, yet they shall not let their locks grow long; they shall only trim the hair of their heads.
21 "Nor shall any of the priests drink wine when they enter the inner court.
22 "And they shall not marry a widow or a divorced woman but shall take virgins from the offspring of the house of Israel, or a widow who is the widow of a priest.
