'Definitely' in the Bible

David said, "LORD God of Israel. Your servant has definitely heard that Saul intends to come to Keilah to destroy the town because of me.

David sent out spies, and he knew that Saul was definitely coming.

The LORD told David, "Pursue them! You will definitely overtake them and rescue the captives." So David and 600 men who were with him set out. They came to the Wadi Besor where those who were left behind stayed.
