'Go Over' in the Bible

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

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

And the king answered, Chimham shall go over with me, and I will do to him that which shall seem good to thee: and whatever thou shalt require of me, that will I do for thee.
