'Truly' in the Bible

Let your ear now take note and let your eyes be open, so that you may give ear to the prayer of your servant, which I make before you at this time, day and night, for the children of Israel, your servants, while I put before you the sins of the children of Israel, which we have done against you: truly, I and my father's people are sinners.

And I went to the house of Shemaiah, the son of Delaiah, the son of Mehetabel, who was shut up; and he said, Let us have a meeting in the house of God, inside the Temple, and let the doors be shut: for they will come to put you to death; truly, in the night they will come to put you to death.

Truly, for forty years you were their support in the waste land, and they were in need of nothing; their clothing did not get old or their feet become tired.
