Ibn Ezra on Exodus 29:15/אבן עזרא על שמות כ״ט:ט״ו
אואת, האחד. מהשנים איזה מהן שירצה:
1THOU SHALT ALSO TAKE THE ONE RAM. Any one of the two rams which you decide to choose.75 (the one) is short for ha-echad me-hashenayim (one of the two). I.E. comments thus because the one ram seems to imply that Scripture has a specific ram in mind.
