Behavior is a person’s outward manner, conduct, demeanor, and deportment. It may describe mental and outward behavior, as in David’s feigned madness, or orderly and reverent conduct expected of Christian leaders, women, and believers.
David’s behavior before the king of Gath is described as feigned madness. In the New Testament, good behavior means an orderly and modest life, reverent demeanor, and conduct becoming holiness, especially in a Christian overseer and in older women.
The biblical terms behind behavior include ideas of taste, judgment, understanding, order, demeanor, and deportment. The entry emphasizes that outward habits and gestures can express an inward reverent spirit.
