Out of the smoke came locusts upon the earth, and power was given to them, as the scorpions of the earth have power.

 Good morning. Continuing the thought of destroying fortresses. Just what kind of fortresses is Paul talking about? We are destroying speculations and every lofty thing raised up against the knowledge of God, and we are taking every thought captive to the obedience of Christ. Those are the fortresses we are destroying; and they truly are fortresses. They are not easily brought down. That is why we need the power of the Holy Spirit. Moving on to Chapter 11: but I am afraid, lest as the serpent deceived Eve by his craftiness, your minds should be lead astray from the simplicity and purity of devotion to Christ. This is very true in some realms of Christianity. They are so in enamored with the thought of obtaining special knowledge (remember Gnosticism?), that they no longer concentrate on the simple truth – that of devotion to Christ. They want to "move on" from the foundation mentioned in Hebrews. If the foundation is not solid, the building will fall. When you are seeking this special knowledge, you open yourself up to deception from the enemy. Paul echoes this as he continues: for if one comes and preaches another Jesus whom we have not preached, or you receive a different spirit which you have not received, or a different gospel which you have not accepted, you bear this beautifully. Sometimes "evangelists or apostles" come to a congregation and try to sway them after themselves. They have the "true knowledge". They flatter the pastors saying they are something special, and are not appreciated. That even call them apostles. It's hard to refute someone who calls you an apostle, especially if you feel under appreciated. Thank You Father that the reader follows after You with his/her whole heart. He/she effectively destroys all the fortresses of speculations raised up against the knowledge of You. He/she takes every thought captive to the obedience of Christ.
