Deuteronomy 18 and Moses' Successor

Is it true that Deuteronomy 18 is the only passage in the Pentateuch that speaks abstractly about a successor to Moses?

• Numbers 27:12-23, Deuteronomy 31 and 34:9 present Joshua as Moses' successor, but I'm looking for passages that talk about a transfer of leadership without mentioning Joshua (or someone else) by name.
• Deuteronomy 17:14-20 provide instructions about kings, but Deuteronomy doesn't view kingship positively or present it as succession.
• Deuteronomy 17:9, 12 mentions "the judge who is in office in those days," but again a direct connection with Moses is not made explicit.

What am I missing?
