ליטעראַטור פֿון בית שני אויף בראשית 28:13

[159] He, then, that stands upon the stairway of heaven says to him who beholds the dream-vision, “I am the Lord God of Abraham thy father and the God of Isaac: fear not” (Gen. 28:13). This oracle was the fort and most firm buttress of the practising soul. It clearly taught him that He Who is Lord and God of the universe is both Lord and God of his family, registered under both titles as held by father and grandfather, to the end that the world at large and the lover of virtue may have the same inheritance: for it has been said, “the Lord Himself is his inheritance”  (Deut. 10:9).

[166] The notable examples which may be used to shew these are countless. The text just quoted is one of them. For the oracle spoke of the man, who in kin was the Practiser’s grandfather, as his father; but did not, when mentioning his actual father, give him the title of parent. The words are: “I am the Lord God of Abraham thy father”—and yet he was his grandfather—and again, “the God of Isaac” (Gen. 28:13), without the addition of “thy father.”

[173] So, after saying “I am the Lord God of Abraham thy father and the God of Isaac,” he adds “fear not” (Gen. 28:13). The words come naturally after the others; for how shall we any longer be afraid, when we have Thee our Defender, a weapon that brings deliverance from fear and every passion? Moreover, it was Thou that didst bring out of obscurity into distinctness the original patterns of our education, Abraham whose teacher, and Isaac whose parent  Thou wast: for Thou didst condescend to be named instructor of the one and father of the other, giving one the position of pupil, the other that of son.
