In all their journeyings the ark containing the law of God was to lead the way. The place of their encampment was indicated by the descent of the pillar of cloud. As long as the cloud rested over the tabernacle, they remained in camp. When it lifted, they pursued their journey. Both the halt and the departure were marked by a solemn invocation. "It came to pass, when the ark set forward, that Moses said, Rise up, Lord, and let Thine 39 enemies be scattered. . . . And when it rested, he said, Return, O Lord, unto the many thousands of Israel." Numbers 10:35, 36.

Under alle deres vandringer skulle arken, der indeholdt Guds lov, være deres vejviser. Det sted, hvor de skulle slå lejr, blev angivet ved, at skystøtten sænkede sig. Så længe skyen hvilede over tabernaklet, forblev de i lejren. Når den hævede sig, fortsatte de deres vandring. Både standsningen og afrejsen blev betegnet ved en højtidelig påkaldelse. »Og hver gang arken brød op, sagde Moses: Stå op, Herre at dine fjender må splittes. ..... Og hver gang den standsede, sagde han: Vend tilbage, Herre, til Israels stammers titusinder!« 4Mos. 10,35-36.
