And he built there an altar, and called the place Elbethel: because there God appeared unto him, when he fled from the face of his brother. El-beth-el - אל בית אל the strong God, the house of the strong God. But the first אל el is wanting in one of De Rossi's MSS., as it is also in the Septuagint, Vulgate, Syriac, and some copies of the Arabic. The sentence reads much better without it, and much more consistent with the parallel passages.
