'Certainly' in the Bible

But he said to him, "Look, a man of God [is] in this town, and the man [is] honored. All that he says certainly comes true. So then let us go there; perhaps he will tell us about our journey on which we have gone."

For as Yahweh lives, who delivers Israel, [I swear] that even if it [is] in Jonathan my son, {he will certainly die}!" But nobody from all the army answered him.

Then Saul said, "So may God do [to me] and {more}, you will certainly die today, Jonathan!"

David said to Jonathan, "Look, tomorrow [is] the new moon, and I should certainly sit with the king to eat. You must send me away so that I can hide myself in the field until the third evening.

Then the king said, "You must certainly die, Ahimelech, you and all your father's household!"

Then David said to Abiathar, "I knew on that day that Doeg the Edomite was there, that he would certainly tell Saul. {I am responsible for the deaths of all your father's household}!

So now then, look, I know that you will certainly be king and the kingdom of Israel will be established in your hand.

And David said, "{As Yahweh lives}, {certainly} Yahweh will strike him, or his day will come and he will die, or he will go down in the battle and {perish}.

Then David {thought to himself}, "Now I will perish one day by the hand of Saul! There is nothing better for me but [that] I must certainly escape to the land of [the] Philistines. Then Saul will desist from searching for me further in all of the territories of Israel, and so I will escape from his hand."

{Now} in those days [the] Philistines gathered their forces for war to fight against Israel. So Achish said to David, "Certainly you realize that you must go out with me in the army, you and your men."

So Achish called David and said to him, "{As Yahweh lives}, certainly you were honest, and {I am pleased to have you marching with me} in the campaign. For I have not found any wrong in you from the day you came to me until this day, but in the eyes of the rulers, you [are] not good.

And David inquired of Yahweh, saying, "Should I pursue after this band [of raiders]? Will I overtake them?" He said to him, "Pursue [them], for you will certainly overtake them, and you will certainly rescue them."
