Rabbi Levi (or others say Rabbi Tanhuma in the name of Rabbi Levi) said that to Abraham, whose spiritual strength was great, they looked like men (as Abraham was as familiar with angels as with men).
अरबी में इसे "अल-रास अल-तूअम अल-मुक़ादिम" (رأس التوأم المقدم‎) कहते हैं, जिसका अर्थ है "आगे वाले जुड़वाँ (व्यक्ति या बच्चे) का सर"।
