She dwelleth and abideth on the rock, upon the crag of the rock, and the strong place. Upon the crag of the rock - שן סלע shen sela, the tooth of the rock, i.e., some projecting part, whither adventurous man himself dares not follow her.
And the strong place - ומצודה umetsudah. Mr. Good translates this word ravine, and joins it to Job 39:29, thus: "And thence espieth the ravine: her eyes trace the prey afar off."
