'Certainly' in the Bible

And David inquired of Yahweh, saying, "Shall I go up to the Philistines? Will you give them into my hands?" Yahweh said to David, "Go up, for {I will certainly give} [the] Philistines into your hand."

Then David said to him, "Don't be afraid, for {I will certainly show} loyal love to you for the sake of Jonathan your father, and I will restore to you all the lands of Saul your father. And you shall always eat food at my table."

But because you have {utterly scorned} Yahweh in this matter, the son born for you {will certainly die}."

For {we must certainly die}, and [we are] as the waters spilled to the ground which cannot be gathered. God will not take a life but devises plans for a banished person not to be cast out from him.

And he [is] also a {valiant warrior}, whose heart [is] like the heart of the lion. He will {certainly melt} with fear, for all Israel knows that your father [is] a mighty warrior and [those] who [are] with him [are] {valiant warriors}.

David sent forth a third of the troops {under the command of Joab}, and a third {under the command of Abishai}, the brother of Joab, the son of Zeruiah, and the remaining third {under the command of Ittai} the Gittite. And the king said to the troops, "I, even I, {will certainly go out} with you."

Then the king said to Araunah, "No, but {I will certainly buy} it from you for a price; I don't want to offer to Yahweh my God burnt offerings that cost me nothing." So David bought the threshing floor and the cattle for fifty shekels of silver.
