One thought is that meekness is strength under control. In this perspective, we see Jesus as a preeminent example of meekness (Matthew 11:29).
We also see meek as showing patience and humility (James 3:13): a calm temper of mind, that is not easily provoked.
Moses, the great leader of ancient Israel, was characterized as being meek. Even more so, Jesus himself claimed to be meek. Plus, Paul taught that meekness is a trait followers of Jesus are encouraged to pursue.
In a biblical context, meekness is not weakness or being easily imposed upon.
