'Course' in the Bible

David answered him, “I swear that women are being kept from us, as always when I go out to battle. The young men’s bodies are consecrated even on an ordinary mission, so of course their bodies are consecrated today.”

Was today the first time I inquired of God for him? Of course not! Please don’t let the king make an accusation against your servant or any of my father’s household, for your servant didn’t have any idea about all this.”

At that time, the Philistines brought their military units together into one army to fight against Israel. So Achish said to David, “You know, of course, that you and your men must march out in the army with me.”
