Or HaChaim on Genesis 35:15/אור החיים על בראשית ל״ה:ט״ו

1 ויקרא יעקב….בית אל. Jacob called… it Bet El. This is difficult. We had been told this previously; even the additional word "El" had already been mentioned in verse 4. Perhaps the Torah means that at this time Jacob enlarged the area which he had previously named Bet El. Perhaps this is alluded to in the otherwise superfluous words "the name of the place that G'd spoke to him." He clearly referred to the difference between having experienced a dream with a divine message many years ago, and the present revelation where G'd appears to have addressed Jacob when he was awake.
