'Surely' in the Bible

After he left, his servants returned. When they saw [that] the doors of the upper room [were] locked, {they thought}, "Surely he [is] {relieving himself} in the cool inner room."

She said, "Surely I will go with you; however, there will be no glory for you in {the path you are taking}, for Yahweh will sell Sisera into [the] hand of a woman." And Deborah stood up and went with Barak to Kedesh.
