'Successor' in the Bible

and now, swear to me by God here: thou dost not lie to me, or to my continuator, or to my successor; according to the kindness which I have done with thee thou dost with me, and with the land in which thou hast sojourned.'

He hath no continuator, Nor successor among his people, And none is remaining in his dwellings.

And I have risen up against them, (The affirmation of Jehovah of Hosts,) And have cut off, in reference to Babylon, Name and remnant, and continuator and successor, The affirmation of Jehovah.
