'Surely' in the Bible

Say to them, 'As I live, says the Lord, I will surely do to you just what you have spoken in my hearing.

I, the Lord, have said, "I will surely do so to all this evil congregation that has gathered together against me. In this wilderness they will be finished, and there they will die!"'"

Then the Lord said to Moses, "The man must surely be put to death; the whole community must stone him with stones outside the camp."

For the Lord had said of them, "They will surely die in the wilderness." And there was not left a single man of them, except Caleb son of Jephunneh and Joshua son of Nun.

"But if he hits someone with an iron tool so that he dies, he is a murderer. The murderer must surely be put to death.

If he strikes him by throwing a stone large enough that he could die, and he dies, he is a murderer. The murderer must surely be put to death.

Or if he strikes him with a wooden hand weapon so that he could die, and he dies, he is a murderer. The murderer must surely be put to death.

or with enmity he strikes him with his hand and he dies, the one who struck him must surely be put to death, for he is a murderer. The avenger of blood must kill the murderer when he meets him.

Moreover, you must not accept a ransom for the life of a murderer who is guilty of death; he must surely be put to death.
