Numbers 1:52-54

Young's Literal Translation

⁵² And the sons of Israel have encamped, each by his camp, and each by his standard, by their hosts;

⁵³ and the Levites encamp round about the tabernacle of the testimony; and there is no wrath on the company of the sons of Israel, and the Levites have kept the charge of the tabernacle of the testimony.

⁵⁴ And the sons of Israel do according to all that Jehovah hath commanded Moses; so they have done.
