Numbers 1:51-53

The Voice

⁵¹ When it’s time to move, it will be the Levites who pack up that tent; they are the ones who shall set it back up. If any outsider tries to get involved, he will be killed. ⁵² The rest of the Israelites will camp according to their troops, each extended family under its own banner. ⁵³ Remember: only the Levites shall camp around the congregation tent that houses the terms of the covenant, guarding and servicing that place to spare the Israelites an outbreak of My wrath.
