'Indeed' in the Bible

"The priest is to administer this oath to the woman: "If indeed another man didn't have sexual relations with you and you didn't become unfaithful to your husband, then may you be free from these waters that bring a curse.

I, the LORD, have spoken. I will indeed do this to this evil congregation, who gathered together against me. They'll be eliminated in this wilderness and will surely die."

Then the LORD told Aaron, "Look! I am indeed placing you in charge of my raised offerings and the holy things concerning the Israelis. Because of your anointing, I'm giving you and your sons a prescribed portion forever.
