Heb. ‘aśah, “to do,” “to make,” “take action” (RSV). As in v. 28, “exploits” is a supplied word. This passage doubtless refers to those who, within lands under the jurisdiction of Rome and beyond, resisted the papal encroachments and maintained a bright faith as, for example, the Waldenses, the Albigenses, and others.

The true church is distinguished not only in that God’s people react against sin by withstanding temptation, but even more in that they carry forward a positive program of action for Him. Christianity cannot be passive. Every child of God has a commission to perform.

 Heb. chalaqqoth, “smooth, slippery things” (see ch. 8:25). It has ever been Satan’s method to make his way appear easier than God’s. Throughout Christian history God’s own people have clung to the road described by Christ when He said, “Narrow is the way, which leadeth unto life” (Matt. 7:14).

That is, the papacy.
