'Help Me' in the Bible

And David went out to meet them, and answered and said to them, If ye have come peaceably to me to help me, my heart shall be knit to you: but if ye have come to betray me to my enemies, seeing there is no wrong in my hands, the God of our fathers look on it, and rebuke it.

And he said, If the Syrians shall be too strong for me, then thou shalt help me: but if the children of Ammon shall be too strong for thee, then I will help thee.
