<p>5:4 <i>And no one takes this honour to himself, but only when he is called by God, even as was Aaron</i>- The Lord was likewise &quot;called&quot; and was not self-appointed; but the similarity then turns to contrast when we realize that He was not of the tribe of Levi, and was appointed not by birth from the tribe of Levi but through having been begotten at resurrection from the dead (:5). He was 'called' by reason of being the son of God, not the son of Levi through Aaron.</p>
