1 Samuel 23:28

23:28 So Saul stopped pursuing David and went to confront the Philistines. Therefore that place is called Sela Hammahlekoth. ¹ 

[23:28]  ¹ sn The name הַמַּחְלְקוֹת סֶלַע (Sela Hammakhleqoth) probably means “Rock of Divisions” in Hebrew, in the sense that Saul and David parted company there (cf. NAB “Gorge of Divisions”; TEV “Separation Hill”). This etymology assumes that the word derives from the Hebrew root II חלק (khlq, “to divide”; HALOT 322 s.v. II חלק). However, there is another root I חלק, which means “to be smooth or slippery” (HALOT 322 s.v. I חלק). If the word is taken from this root, the expression would mean “Slippery Rock.”
