In 2 Chronicles 29:5, Hezekiah commands the Levites to sanctify themselves and cleanse the temple — this verse shows them obeying that command.

2 Chronicles 30:15 describes Levites sanctifying themselves for Hezekiah's Passover — same reform, same action.

2 Chronicles 35:6 has Josiah commanding the Levites to sanctify themselves for Passover — a later parallel to Hezekiah's command.

2 Chronicles 5:11 notes priests were sanctified at Solomon's temple dedication — a parallel sanctification for temple service.

2 Chronicles 30:12 similarly says the people acted by the king's command and the LORD's word, echoing the same obedience phrase used here.

1 Chronicles 15:14 records priests and Levites sanctifying themselves to move the ark — the same self-sanctification act for a holy task.

Nehemiah 13:9 recounts cleansing temple chambers from defilement — a similar act of temple purification.

1 Chronicles 23:28 defines the Levites' duty including purifying holy things — this verse shows them doing that work.
