Shared ground
These verses end Ruth by switching from story to a short genealogy: a named line of descent beginning with Perez and ending with David (Ruth 4:18–22). The repeated “became the father of” language (Hebrew verb behind “begat,” ) highlights continuity across generations rather than describing events.
In the immediate story, the genealogy confirms that the threatened family line did, in fact, continue: Boaz is linked to Obed, then Jesse, then David. In the wider setting of Israel “in the days when the judges ruled,” this list also signals that the book’s small-scale family restoration fits into Israel’s longer remembered history.
Where interpretation differs
The main questions are how this genealogy functions and how complete it is.
Some read it as a careful historical record intended to be taken as a full chain of direct father-to-son links for each step. Others think it is a selective, representative genealogy that can skip generations while still truthfully tracing descent.
Why the disagreement exists
The text itself is very spare: it gives names and the repeated fathering formula, but it does not explain whether any generations are omitted or why the list starts where it does. Also, biblical genealogies elsewhere sometimes compress lines for focus or memorability, so readers bring different expectations to what “father of” is meant to communicate here.
What this passage clearly contributes
Explicitly, the passage claims a descent line: Perez → Hezron → Ram → Amminadab → Nahshon → Salmon → Boaz → Obed → Jesse → David. As an inference from its placement, the book uses this ending to widen the meaning of Ruth’s outcome: what happened to Naomi, Ruth, and Boaz is presented as part of the ancestry of Israel’s later king, David, tying a domestic resolution in Bethlehem to national memory and leadership.
