'Indeed' in the Bible

Indeed a man shall take hold of his brother in the house of his father, saying, "You have clothing, you be our ruler, and let this ruin be under your hand."

He said, "Go, and tell this people, 'You hear indeed, but don't understand; and you see indeed, but don't perceive.'

Don't fear, neither be afraid. Haven't I declared it to you long ago, and shown it? You are my witnesses. Is there a God besides me? Indeed, there is not. I don't know any other Rock."
