The families of the Gershonites shall pitch behind the tabernacle westward.
Numbers 1:53
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.
And the tent of meeting -- the camp of the Levites -- hath journeyed in the midst of the camps; as they encamp so they journey, each at his station by their standards.
