'Power' in the Bible

In the womb he took his brother by the heel; and in his manhood he had power with God:

yea, he had power over the angel, and prevailed; he wept, and made supplication unto him: he found him at Beth-el, and there he spake with us,

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