ליטעראַטור פֿון בית שני אויף בראשית 31:13

Yet there can be no cowering fear for the man who relies on the hope of the divine comradeship, to whom are addressed the words “I am the God who appeared to thee in the place of God” (Gen. 31:13).

[238] Why, then, do we wonder any longer at His assuming the likeness of angels, seeing that for the succour of those that are in need He assumes that of men? Accordingly, when He says “I am the God who was seen of thee in the place of God” (Gen. 31:13), understand that He occupied the place of an angel only so far as appeared, without changing, with a view to the profit of him who was not yet capable of seeing the true God.

[241] Hence it is that He Himself says “I am the God,” whose image thou didst aforetime behold deeming it to be I Myself, and didst dedicate a pillar engraved with a most holy inscription  (Gen. 31:13); and the purport of the inscription was that I alone am standing (Ex. 17:6) and that it was I alone that established the being of all things, bringing confusion and disorder into order and array, and sustained the universe to rest firm and sure upon the mighty Word, who is My viceroy.
