Job 39:28

Upon the crag of the rock - סלע שן 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."
