Found numerous times in Matthew-Revelation, the Greek verb “didasko” meant “teach.” As illustrated by Mt. 4:23; 5:2; 26:55; Mk. 8:31; Lk. 11:1, one of Jesus’ primary tasks was teaching. Jesus said the Holy Spirit would come and “teach” the apostles “all things” (Jn. 14:26). Jewish officials did not want the apostles to “speak or teach” about Jesus (Acts 4:18). Christians did not “cease teaching” the Christian faith (Acts 5:42) and persistence allowed “much people to be taught” (Acts 11:26). Teaching was done in “every church” (1 Cor. 4:17) to assure doctrinal unity. Even “nature” can do some “teaching” (1 Cor. 11:14). Singing is designed to teach (Col. 3:16), and women are forbidden from “teaching” in the sense of usurping authority over men (1 Tim. 2:12). There is a need to “teach others also” (2 Tim. 2:2) lest people need “taught again” (Heb. 5:12). Some “teaching” is evil (Rev. 2:14, 20).
