'Indeed' in the Bible

(He gave instructions that the people of Judah should be taught "The Bow." Indeed, it is written down in the Book of Yashar.)

So David asked the Lord, "Should I march up against the Philistines? Will you hand them over to me?" The Lord said to David, "March up, for I will indeed hand the Philistines over to you."

David then sent out the army -- a third under the leadership of Joab, a third under the leadership of Joab's brother Abishai son of Zeruiah, and a third under the leadership of Ittai the Gittite. The king said to the troops, "I too will indeed march out with you."

Indeed, you are my lamp, Lord. The Lord illumines the darkness around me.

Indeed,with your help I can charge against an army; by my God's power I can jump over a wall.

Indeed, who is God besides the Lord? Who is a protector besides our God?
