'Surely' in the Bible

She said, "Just as surely as you are alive, my lord, I am the woman who previously stood here with you in order to pray to the Lord.

For as surely as the Lord, the deliverer of Israel, lives, even if it turns out to be my own son Jonathan, he will certainly die!" But no one from the army said anything.

But the army said to Saul, "Should Jonathan, who won this great victory in Israel, die? May it never be! As surely as the Lord lives, not a single hair of his head will fall to the ground! For it is with the help of God that he has acted today." So the army rescued Jonathan from death.

Then Samuel said, "Bring me King Agag of the Amalekites." So Agag came to him trembling, thinking to himself, "Surely death is bitter!"

When they arrived, Samuel noticed Eliab and said to himself, "Surely, here before the Lord stands his chosen king!"

Now as Saul watched David going out to fight the Philistine, he asked Abner, the general in command of the army, "Whose son is this young man, Abner?" Abner replied, "As surely as you live, O king, I don't know."

Saul accepted Jonathan's advice and took an oath, "As surely as the Lord lives, he will not be put to death."

Taking an oath, David again said, "Your father is very much aware of the fact that I have found favor with you, and he has thought, 'Don't let Jonathan know about this, or he will be upset.' But as surely as the Lord lives and you live, there is about one step between me and death!"

When I send a boy after them, I will say, "Go and find the arrows." If I say to the boy, 'Look, the arrows are on this side of you; get them,' then come back. For as surely as the Lord lives, you will be safe and there will no problem.

But the king said, "You will surely die, Ahimelech, you and all your father's house!

"Now, my lord, as surely as the Lord lives and as surely as you live, it is the Lord who has kept you from shedding blood and taking matters into your own hands. Now may your enemies and those who seek to harm my lord be like Nabal.

Otherwise, as surely as the Lord, the God of Israel, lives -- he who has prevented me from harming you -- if you had not come so quickly to meet me, by morning's light not even one male belonging to Nabal would have remained alive!"

This failure on your part isn't good! As surely as the Lord lives, you people who have not protected your lord, the Lord's chosen one, are as good as dead! Now look where the king's spear and the jug of water that was by his head are!"

But Saul swore an oath to her by the Lord, "As surely as the Lord lives, you will not incur guilt in this matter!"

So Achish summoned David and said to him, "As surely as the Lord lives, you are an honest man, and I am glad to have you serving with me in the army. I have found no fault with you from the day that you first came to me until the present time. But in the opinion of the leaders, you are not reliable.
