Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

Jacob lived in Egypt for 17 years. He then sent for Joseph, as he felt that his death was approaching; and having requested him, as a mark of love and faithfulness, not to bury him in Egypt, but near his fathers in Canaan, he made him assure him on oath (by putting his hand under his hip, vid., p. 164) that his wishes should be fulfilled. When Joseph had taken this oath, "Israel bowed (in worship) upon the bed's head." He had talked with Joseph while sitting upon the bed; and when Joseph had promised to fulfil his wish, he turned towards the head of the bed, so as to lie with his face upon the bed, and thus worshipped God, thanking Him for granting his wish, which sprang from living faith in the promises of God; just as David also worshipped upon his bed (Kg1 1:47-48). The Vulgate rendering is correct: adoravit Deum conversus ad lectuli caput. That of the lxx, on the contrary, is προσεκύνησεν Ἰσραὴλ ἐπὶ τὸ ἄδρον τῆς ῥάβδου αὐτοῦ (i.e., המּטּה); and the Syriac and Itala have the same (cf. Heb 11:21). But no fitting sense can be obtained from this rendering, unless we think of the staff with which Jacob had gone through life, and, taking αὐτου therefore in the sense of αὑτοῦ, assume that Jacob made use of the staff to enable him to sit upright in bed, and so prayed, bent upon or over it, though even then the expression המטה ראשׁ remains a strange one; so that unquestionably this rendering arose from a false reading of המטה, and is not proved to be correct by the quotation in Heb 11:21. "Adduxit enim lxx Interpr. versionem Apostolus, quod ea tum usitata esset, non quod lectionem illam praeferendam judicaret (Calovii Bibl. illustr. ad h. l.).
