'Pertaineth' in the Bible

And it was told king David, saying, The LORD hath blessed the house of Obededom, and all that pertaineth unto him, because of the ark of God. So David went and brought up the ark of God from the house of Obededom into the city of David with gladness.

Then said the king to Ziba, Behold, thine is all that pertaineth unto Mephibosheth. And Ziba said, I do obeisance; let me find favor in thy sight, my lord, O king.
