'Indeed' in the Bible

[“You shall do this,” said the Lord,] “so that the elders may believe that the Lord, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has [most certainly] appeared to you.”

But if you will indeed listen to and truly obey His voice and do everything that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
