'Firmly' in the Bible

He will be like a tree firmly planted by streams of water,Which yields its fruit in its seasonAnd its leaf does not wither;And in whatever he does, he prospers.

“The earth and all who dwell in it melt;It is I who have firmly set its pillars. Selah.

The Lord reigns, He is clothed with majesty;The Lord has clothed and girded Himself with strength;Indeed, the world is firmly established, it will not be moved.

Say among the nations, “The Lord reigns;Indeed, the world is firmly established, it will not be moved;He will judge the peoples with equity.”
