Exodus 13:19-21

Young's Literal Translation

¹⁹ And Moses taketh the bones of Joseph with him, for he certainly caused the sons of Israel to swear, saying, `God doth certainly inspect you, and ye have brought up my bones from this with you.'

²⁰ And they journey from Succoth, and encamp in Etham at the extremity of the wilderness,

²¹ and Jehovah is going before them by day in a pillar of a cloud, to lead them in the way, and by night in a pillar of fire, to give light to them, to go by day and by night;
