¹ tn Heb “and Saul died because of his unfaithfulness by which he acted unfaithfully against the Lord, concerning the word of the Lord which he did not keep, also to Saul, a ritual pit to seek.” The text alludes to the incident recorded in 1 Sam 28. The Hebrew term אוֹב (’ov, “ritual pit”) refers to a pit used by a magician to conjure up underworld spirits. In 1 Sam 28:7 the witch of Endor is called a בַּעֲלַת־אוֹב (ba’alat-’ov, “owner of a ritual pit”). See H. A. Hoffner, “Second Millennium Antecedents to the Hebrew áo‚b,” JBL 86 (1967): 385-401.
