I survey a bit of the structure of 1 Timothy and the other Pastoral Epistles. I spend most of the time studying out the variations on the word "teach" throughout these 3 New Testament letters. The apostle Paul used the terms to emphasize his concerns on things like getting our teaching right, who is qualified to do it (women's roles in the church), Bible doctrine, strange doctrine, false teaching, working hard at preaching and teaching the Bible, etc.
