Parashas Vayeira · Passuk 22:11
And an angel of Hashem called to him from heaven and said, “Avraham, Avraham.” And he said, “Here I am.”
Torah Temimah points to Torat Kohanim (opening of Vayikra).
TT lemma: אברהם אברהם.
Sefaria — Sifra / Torat Kohanim
English: “Avraham, Avraham.” [This is] a language of affection and a language of urgency.
Derash on the verse (Torat Kohanim) — not a formal named middah of the 13. Repetition of the name carries two simultaneous tones.
The doubled address “Avraham, Avraham” expresses both affection and urgency.
