Passage
and Obed became the father of Jesse, and Jesse became the father of David.
and Obed became the father of Jesse, and Jesse became the father of David.
Ruth 4:20 and Amminadab became the father of Nahshon, and Nahshon became the father of Salmon,
Ruth 4:21 and Salmon became the father of Boaz, and Boaz became the father of Obed,
Ruth 4:22 and Obed became the father of Jesse, and Jesse became the father of David.
The verse centers on "obed", "became", "father", "jesse", and "david". It is saying that the verse draws attention to "obed" and "became", so its meaning should be read from those terms before moving to application.
The prior verse says "and Salmon became the father of Boaz...", giving immediate footing for "obed" and "became". In Ruth context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "obed" and "became" with trust shaped by these words, not by a vague optimism outside the passage.
