Deuteronomy 31:15
And the LORD appeared in the tabernacle in a pillar of a cloud: and the pillar of the cloud stood over the door of the tabernacle. And the LORD appeared in the tabernacle in a pillar of a cloud: and the pillar of the cloud stood over the door of the tabernacle.
At divine direction Moses and Joshua presented themselves together at the tabernacle, where the Lord appeared with the pillar of cloud taking its stand over the entrance. The meeting occurred in the sight of Israel, making the change of leadership an open and witnessed act. There Moses's leadership was brought to an end and Joshua was placed in charge in his stead.
