'Foundations' in the Bible

If the foundations are 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 angry.

Then the channels of waters appeared. The foundations of the world were laid bare at your rebuke, Yahweh, at the blast of the breath of your nostrils.

They don't know, neither do they understand. They walk back and forth in darkness. All the foundations of the earth are shaken.

He laid the foundations of the earth, that it should not be moved forever.
