'Indeed' in the Bible

Now the serpent was more crafty than any other {wild animal} which Yahweh God had made. He said to the woman, "Did God indeed say, 'You shall not eat from any tree in the garden'?"

Then Yahweh said to Abraham, "What [is] this [that] Sarah laughed, saying, 'Is it indeed true [that] I will bear a child, now [that] I have grown old?'

Then Jacob awoke from his sleep and said, "Surely Yahweh {is indeed} in this place and I did not know!"

If the God of my father, the God of Abraham and the Fear of Isaac had not been with me, indeed now you would have sent me away empty-handed. God saw my misery and the labor of my hands and rebuked you last night."

And he told [it] to his father and to his brothers. And his father rebuked him and said to him, "What [is] this dream that you have dreamed? Will I and your mother and your brothers indeed come to bow down to the ground to you?"
