Meekness is an attribute of human nature and behavior. It has been defined several ways: righteous, humble, teachable, and patient under suffering, long suffering willing to follow gospel teachings; an attribute of a true disciple.
“inherit the Earth” is also similar to “theirs is The Kingdom of Heaven” in Matthew 5:3. … A refined meaning of this phrase has been seen to say that those that are quiet or nullified will one day inherit the world. Meek in the Greek literature of the period most often meant gentle or soft.
