1 Chronicles 15:14

So the priests and the Levites sanctified themselves to bring up the ark of the Lord God of Israel.

Cross-reference

In 1 Chronicles 15:12, David commands the Levites to consecrate themselves — this verse records their obedience to that command.

In Leviticus 10:3, God declares He must be proven holy by those who approach Him — the consecration here follows that principle.

In 2 Chronicles 29:15, the priests consecrate themselves to cleanse the temple — a parallel action of sanctifying for holy service.

Joel 2:16 Parallel

In Joel 2:16, a similar call to consecrate the congregation appears — both emphasize sanctification before approaching God, though Joel's context is national repentance.
