'Surely' in the Bible

thou art not afraid of them; thou dost surely remember that which Jehovah thy God hath done to Pharaoh, and to all Egypt,

'But thou dost surely kill him; thy hand is on him, in the first place, to put him to death, and the hand of all the people last;

Thou dost surely smite the inhabitants of that city by the mouth of the sword; devoting it, and all that is in it, even its cattle, by the mouth of the sword;

for I -- I have known thy rebellion, and thy stiff neck; lo, in my being yet alive with you to-day, rebellious ye have been with Jehovah, and also surely after my death.
