'Surely' in the Bible

I told them of the good hand of my God that was upon me and surely the words of the king that were spoken to me. And they said, "Let us arise and build!" And they strengthened their hands for [this] good work.

Then I went to the house of Shemaiah son of Delaiah, the son of Mehetabel. He was confined to his home. He said, "Let's set up a time to meet in the house of God, within the temple. Let's close the doors of the temple, for they are coming to kill you. It will surely be at night that they will come to kill you."

Then I perceived that surely God had not sent him, but he uttered his prophecy against me because Tobiah and Sanballat had hired him.
