'Foundations' in the Bible

If the foundations be destroyed, What can the righteous do?

Then the earth shook and trembled; The foundations also of the mountains quaked And were shaken, because he was wroth.

Then the channels of waters appeared, And the foundations of the world were laid bare, At thy rebuke, O Jehovah, At the blast of the breath of thy nostrils.

They know not, neither do they understand; They walk to and fro in darkness: All the foundations of the earth are shaken.

Who laid the foundations of the earth, That it should not be moved for ever.
