Passage
And the sons of Caleb the son of Jephone, were Hir, and Ela, and Naham. And the sons of Ela: Cenez.
And the sons of Caleb the son of Jephone, were Hir, and Ela, and Naham. And the sons of Ela: Cenez.
1 Chronicles 4:13 And the sons of Cenez were Othoniel, and Saraia. And the sons of Othoniel, Hathath, and Maonathi.
1 Chronicles 4:14 Maonathi begot Ophra, and Saraia begot Joab the father of the Valley of artificers: for artificers were there.
1 Chronicles 4:15 And the sons of Caleb the son of Jephone, were Hir, and Ela, and Naham. And the sons of Ela: Cenez.
1 Chronicles 4:16 The sons also of Jaleleel: Ziph, and Zipha, Thiria and Asrael.
1 Chronicles 4:17 And the sons of Esra, Jether, and Mered, and Epher, and Jalon, and he begot Mariam, and Sammai, and Jesba the father of Esthamo.
The verse centers on "sons", "caleb", "jephone", "naham", and "cenez". It is saying that the verse draws attention to "sons" and "caleb", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "Maonathi begot Ophra and Saraia begot Joab..." into verse 16's "The sons also of Jaleleel Ziph and...", so "sons" and "caleb" belong inside that flow. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "sons" and "caleb" with trust shaped by these words, not by a vague optimism outside the passage.
