“On the south side shall be the standard of the forces with Reuben according to their armies, and the leader of the children of Reuben shall be Elizur the son of Shedeur.”
Now the sons of Reuben the firstborn of Israel—he was indeed the firstborn, but because he defiled his father’s bed, his birthright was given to the sons of Joseph, the son of Israel, so that the genealogy is not listed according to the birthright;
and as the sacrifice of peace offerings: two oxen, five rams, five male goats, and five male lambs in their first year. This was the offering of Elizur the son of Shedeur.
When you sound the advance the second time, then the camps that lie on the south side shall begin their journey; they shall sound the call for them to begin their journeys.
