“He said: Lord, God of my master Abraham, please arrange it for me today, and perform kindness with my master Abraham” (Genesis 24:12). “He said: Lord, God of my master Abraham, please arrange it for me today…” “Who among you fears the Lord, who heeds the voice of His servant…” (Isaiah 50:10). “Who among you fears the Lord” – this is Abraham;1See Genesis 22:12. “who heeds the voice of His servant…” – [this means] that the Holy One blessed be He heeded the voice of his [Abraham’s] servant.
“Who walked in darkness” (Isaiah 50:10) – as he came forth from Mesopotamia and its environs, but he did not know where he was to go, like a person who is situated in the dark. “And there was no light for him” (Isaiah 50:10) – and who provided illumination for him? The Holy One blessed be He provided illumination for him every place that he would go. “Let him trust in the name of the Lord and rely on his God” (Isaiah 50:10) – “[You called his name Abraham,] and You found his heart faithful before You” (Nehemiah 9:7–8).
Another interpretation, “Who among you fears the Lord” – this is Eliezer; “who heeds the voice of His servant…” – [he heeded] the voice of Abraham who was the servant of the Holy One blessed be He, as it is stated: “For the sake of My servant, Abraham” (Genesis 26:24). “Who walked in darkness” – when he went to bring Rebecca. “And there was no light for him” – and who provided illumination for him?
The Holy One blessed be He provided illumination for him, with shooting stars and lightning. “Let him trust in the name of the Lord and rely on his God” – “He said: Lord, God of my master Abraham, please arrange it for me today.”
