'Power' in the Bible

He took his brother by the heel in the womb, and by his strength he had power with God:

Yea, he had power over the angel, and prevailed: he wept, and made supplication unto him: he found him in Bethel, and there he spake with us;

I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction: repentance shall be hid from mine eyes.
