There are three things in the text worthy of our observation. The first is fortresses demolished, “casting down imaginations and every high thing that exalts itself against the knowledge of God.” Secondly, prisoners seized, “bringing into captivity every thought,” and thirdly, prisoners led away captive—for
such is the force of the Greek, “bringing into captivity every thought to the obedience of Christ”—as if the captured ones were taken away and put under new service to the anointed Prince.
C.H. Spurgeon
