John Wesley on Joshua 23:13

Traps to you - By your converse with them, you will be drawn by degrees into their errors, and impieties, and brutish lusts. Thorns in your eyes - When they have seduced, and thereby weakened you, then they will molest and vex you, no less than a severe scourge doth a man's sides which are lashed by it, or than a small thorn doth the eye when it is got within it. Till ye perish - They shall so persecute you, and fight against, you with such success, that you shall be forced to quit your own land, and wander you know not whither; which must needs be very terrible to them to think of, when they compared this present ease, and plenty and safety, with the pains, and weariness, and hazards, and wants of their former wanderings.
