'Three Days' in the Bible

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;

And they journey from Pi-Hahiroth, and pass over through the midst of the sea, into the wilderness, and go a journey of three days in the wilderness of Etham, and encamp in Marah.
