'Go Over' in the Bible

Then said Abishai the son of Zeruiah unto the king, Why should this dead dog curse my lord the king? let me go over, I pray you, and take off his head.

Let your servant, I pray you, turn back again, that I may die in my own city, and be buried by the grave of my father and of my mother. But behold your servant Chimham; let him go over with my lord the king; and do to him what shall seem good unto you.

And the king answered, Chimham shall go over with me, and I will do to him that which shall seem good unto you: and whatsoever you shall ask of me, that will I do for you.
