Numbers 10:33-35

Young's Literal Translation

³³ And they journey from the mount of Jehovah a journey of three days; and the ark of the covenant of Jehovah is journeying before them the journey of three days, to spy out for them a resting-place;

³⁴ and the cloud of Jehovah [is] on them by day, in their journeying from the camp.

³⁵ And it cometh to pass in the journeying of the ark, that Moses saith, `Rise, O Jehovah, and Thine enemies are scattered, and those hating Thee flee from Thy presence.'
