'Immovable' in the Bible

The folds of his flesh are joined together,solid as metal and immovable.

Man cannot be made secure by wickedness,but the root of the righteous is immovable.

But they struck a sandbar and ran the ship aground. The bow jammed fast and remained immovable, while the stern began to break up by the pounding of the waves.

Therefore, my dear brothers, be steadfast, immovable, always excelling in the Lord’s work, knowing that your labor in the Lord is not in vain.
