Passage
The sonnes of Iudah were Pharez, Hezron, and Carmi, and Hur, and Shobal.
The sonnes of Iudah were Pharez, Hezron, and Carmi, and Hur, and Shobal.
1 Chronicles 4:1 The sonnes of Iudah were Pharez, Hezron, and Carmi, and Hur, and Shobal.
1 Chronicles 4:2 And Reaiah the sonne of Shobal begat Iahath, and Iahath begate Ahumai, and Lahad: these are the families of the Zoreathites.
1 Chronicles 4:3 And these were of the father of Etam, Izreel, and Ishma and Idbash: and the name of their sister was Hazelelponi.
The verse centers on "sonnes", "iudah", "pharez", "hezron", "carmi", and "shobal". It is saying that the verse draws attention to "sonnes" and "iudah", so its meaning should be read from those terms before moving to application.
The next verse adds "And Reaiah the sonne of Shobal begat...", so "sonnes" and "iudah" should be read forward into that movement. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "sonnes" and "iudah" with trust shaped by these words, not by a vague optimism outside the passage.
