then Moses stood in the gate of the camp and said , Who is on the Lord ’s side? Come to me. And all the sons of Levi gathered around him.

So he stood at the entrance to the camp and said, “Whoever is for the Lord, come to me.” And all the Levites rallied to him.

Then Moses stood in the gate of the camp, and said, Who is on the Lord's side? let him come unto me. And all the sons of Levi gathered themselves together unto him.
