Therefore I also said, I will not drive them out from before you; but they shall be as thorns in your sides, and their gods shall be a snare unto you.

Ruin. Septuagint, "stumbling block "the occasion of ruin. (Menochius)
Thus by a false compassion (Calmet) and negligence, the Israelites brought upon themselves the most serious difficulties, while those whom they had spared, turned against them by a just judgment of God, and proved the ruin both of their souls and bodies, by drawing them into idolatry and then putting them to the sword.
