'Keep' in the Bible

Jonathan said to the attendant who carried his weapons, “Come on, let’s cross over to the garrison of these uncircumcised men. Perhaps the Lord will help us. Nothing can keep the Lord from saving, whether by many or by few.”

So David got up early in the morning, left the flock with someone to keep it, loaded up, and set out as Jesse had instructed him.He arrived at the perimeter of the camp as the army was marching out to its battle formation shouting their battle cry.

“But what have I done?” David replied to Achish. “From the first day I was with you until today, what have you found against your servant to keep me from going along to fight against the enemies of my lord the king?”
