Adam Clarke on 1 Samuel 24:2

Rocks of the wild goats - The original (צורי היעלים tsurey haiyeelim) is variously understood. The Vulgate makes a paraphrase: Super abruptissimas petras quae solis ibicibus perviae sunt; "On the most precipitous rocks over which the ibexes alone can travel." The Targum: the caverns of the rocks. The Septuagint make the original a proper name; for out of צרוי היעלים tsurey haiyeelim, they make Σαδδαιεμ Saddaiem, and in some copies Αειαμειν Aeiamein, which are evidently corruptions of the Hebrew.
