'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 thee, and take off his head.

Let thy servant, I pray thee, turn back again, that I may die in mine 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 unto thee.

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