I have said, Ye are gods; and all of you are children of the most High. Ye are gods - Or, with the prefix of כ ke, the particle of similitude, כאלהים keelohim, "like God." Ye are my representatives, and are clothed with my power and authority to dispense judgment and justice, therefore all of them are said to be children of the Most High.
