Job 9:4 Meaning

2I know it is so of a truth: but how should man be just with God?

3If he will contend with him, he cannot answer him one of a thousand.

4He is wise in heart, and mighty in strength: who hath hardened himself against him, and hath prospered?

5Which removeth the mountains, and they know not: which overturneth them in his anger.

6Which shaketh the earth out of her place, and the pillars thereof tremble.
