Justin Martyr

I shall give you another testimony, my friends, from the Scriptures, that God begat before all creatures a Beginning, [who was] a certain rational power [proceeding] from Himself, who is called by the Holy Spirit, now the Glory of the Lord, now the Son, again Wisdom, again an Angel, then God, and then Lord and Logos; and on another occasion He calls Himself Captain, when He appeared in human form to Joshua the son of Nave (Nun). For He can be called by all those names, since He ministers to the Father's will, and since He was begotten of the Father by an act of will.

For it was not because Moses so prayed that the people were stronger, but because, while one who bore the name of Jesus (Joshua) was in the forefront of the battle, he himself made the sign of the cross. For who of you knows not that the prayer of one who accompanies it with lamentation and tears, with the body prostrate, or with bended knees, propitiates God most of all? But in such a manner neither he nor any other one, while sitting on a stone, prayed. Nor even the stone symbolized Christ, as I have shown.

For it was not without design that the prophet Moses, when Hur and Aaron upheld his hands, remained in this form until evening. For indeed the Lord remained upon the tree almost until evening, and they buried Him at eventide; then on the third day He rose again.
