The Camp

Numbers 2:1-34
The Israelites are to camp around the tent of meeting some distance from it, each of them under their standard and holding the banners of their family.
On the east the divisions of the camp of Judah, next to them is tribe of Issachar, Zebulun will be next.
All men assigned to the camp of Judah. They will set out first.
On the south be the divisions of the camp of Reuben, Simon will camp next to them, Gad will be next.
The camp of the Levites will set out in the middle of the camps. They will set out in the same order as they encamp, each in their own place under their standard.
On the west will be the divisions of the camp of Ephraim. The tribe of Manasseh will be next to them, tribe of Benjamin will be next.
On the north will be the divisions of the camp of Dan, Asher will camp next to them, Naphtali will be next.
The arrangement of four groups of three tribes is the same for camping and for marching. When the nation moved, the three eastern bribes, headed by Judah, led the way.
10:17 gives a slightly different order for the middle section - Gershonites and Merarites carrying God's Tent, then Reuben, Simeon and Gad, followed by the Kohathites with the furnishings. The northern tribes, Dan, Asher and Naphtali bring up the rear. The tribe's leaders are the same as those who helped in the census.
Why?
God arranged this camp sequences, Moses follow God's command. So there was the order among tribes of Israelite.
God's work has his order, and Tent of meeting is the center of Israel, for the Lord is their God and their blessing. But everyone have to keep some distance from it, for God is Holy and men are unclean, in order to protect their life, keep some distance is needed.
How?
Does God is my center in my daily life? Yes, I do know it,
