'Far' in the Bible

Then King David went in and sat [in prayer] before the Lord, and said, “Who am I, O Lord God, and what is my house (family), that You have brought me this far?

Yet this was very insignificant in Your eyes, O Lord God, for You have spoken also of Your servant’s house (royal dynasty) in the distant future. And this is the law and custom of man, O Lord God.

Joab answered, “Far be it, far be it from me that I would swallow up or destroy!

And he said, “Far be it from me, O Lord, that I should drink this. [Is it not the same as] the blood of the men who went at the risk of their lives?” So he would not drink it. These things the three mighty men did.
