'Firmly' in the Bible

"But in the last days it will come about that the Temple Mount of the LORD will be firmly set as the leading mountain. It will be exalted above its surrounding hills, and people will stream toward it.

"Then he will take his stand, shepherding by means of the strength of the LORD, by the power of the name of the LORD his God. And they will be firmly established; indeed, from then on he will become great to the ends of the earth.
