1 Samuel 14:4 - Matthew Poole's English Annotations on the Holy Bible

The passages; so these might be two known and common passages, both which Jonathan must cross, or pass over, to go to the Philistines, between which the following rocks lay. But the words may be rendered thus, In the middle (for so the Hebrew particle ben signifies, as Isaiah 44:4; and beth, in, is understood by a very frequent ellipsis) of the passage; the plural number being put for the singular, as is frequent. A sharp rock on the one side, and on the other side; which is not so to be understood, as if in this passage one rock was on the right hand, and the other on the left; for so he should have gone between both; and there was no need of climbing up to them, which is mentioned below, 1 Samuel 14:13. But the meaning is, that the tooth (or prominency) of the one rock (as it is in the Hebrew) was on the one side, i.e. northward, looking towards Michmash, (the garrison of the Philistines,) and the tooth of the other rock was on the other side, i.e. southward, looking towards Gibeah, (where Saul's camp lay,) as the next verse informs us; and Jonathan was forced to climb over these two rocks, because the other and common ways from one town to the other might now be obstructed, or were not so fit for his present design.
