Joshua 23:13

know for a certainty that the Lord, your God, will no more drive out any of these nations from before you, an achievement which was possible only with His assistance, but they shall be snares and traps unto you, Numbers 33:55; Isaiah 8:14, and scourges in your sides, to punish them, and thorns in your eyes, infinitely more painful than motes, until ye perish from off this good land which the Lord, your God, hath given you. Joshua heaps the figures picturing the affliction and the misery which would follow their act of disloyalty in entering into friendships and other intimate relationships with the heathen nations; for the Lord knew that no warning could be made too impressive in this connection. The blessings of God's goodness should be the strongest inducement to all Christians to cling to Him alone with all their heart and to shun all intimacy with the children of this world.
