'Further' in the Bible

Then King David sent a message to Zadok and Abiathar the priests saying, "Tell the elders of Judah, 'Why should you delay any further in bringing the king back to his palace, when everything Israel is saying has come to the king's attention.

You are my brothers -- my very own flesh and blood! Why should you delay any further in bringing the king back?'

After all, there was no one in the entire house of my grandfather who did not deserve death from my lord the king. But instead you allowed me to eat at your own table! What further claim do I have to ask the king for anything?"
