John Wesley on 2 Samuel 17:13

Bring ropes - It is an hyperbolical expression, suited to the vain - glorious temper of this insolent young man: implying, that they would do so if they could not destroy him another way: or, that they should be enough to do so, if there were occasion. River - Adjoining to the city; it being usual to build cities near some river, both for defence, and for other accommodations.
