'Really' in the Bible

the Ammonite leaders said to Hanun their lord, “Just because David has sent men with condolences for you, do you really believe he’s showing respect for your father? Instead, hasn’t David sent his emissaries in order to scout out the city, spy on it, and demolish it?”

For your servant made a vow when I lived in Geshur of Aram, saying: If the Lord really brings me back to Jerusalem, I will worship the Lord in Hebron.”
