'Indeed' in the Bible

"Indeed, the Day of the Lord approaches all nations. As you have done it will be done to you your deeds will return to haunt you! so will all nations drink from the cup of my wrath perpetually.

"The house of Jacob will be a fire, and the house of Joseph a flame, but the house of Esau will be kindling. Then Jacob and Joseph will burn and consume Esau, and no survivor will remain from the house of Esau." Indeed, the Lord has spoken it.
