Why do the meek inherit the earth?

Blessed are the meek, for they will inherit the earth.

Matthew 5:5

When Jesus spoke of the meek inheriting the earth he was not talking about people who are weak, lacking in courage, or who cower before others. Meek, sometimes translated as “gentle,” is used in the Bible to denote power under control. It is the power that allowed Moses to repeatedly challenge the ruler of a land in which Moses’ people (the Israelites) were enslaved.

Now the man Moses was very meek, more than all people who were on the face of the earth.

Numbers 12:3 ESV
