Passage
The son of Sellum, the son of Sadoc, the son of Achitob,
The son of Sellum, the son of Sadoc, the son of Achitob,
Ezra 7:1 Now after these things in the reign of Artaxerxes king of the Persians, Esdras the son of Saraias, the son of Azarias, the son of Helcias,
Ezra 7:2 The son of Sellum, the son of Sadoc, the son of Achitob,
Ezra 7:3 The son of Amarias, the son of Azarias, the son of Maraioth,
Ezra 7:4 The son of Zarahias, the son of Ozi, the son of Bocci,
The verse centers on "sellum", "sadoc", and "achitob". It is saying that the verse draws attention to "sellum" and "sadoc", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "Now after these things in the reign..." into verse 3's "The son of Amarias the son of...", so "sellum" and "sadoc" belong inside that flow. In Ezra context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "sellum" and "sadoc" with trust shaped by these words, not by a vague optimism outside the passage.
