Ezra 10:7 And they made proclamation throughout Judah and Jerusalem unto all the children of the captivity, that they should gather themselves together unto Jerusalem;

The verse centers on "ezra", "rose", "before", "house", "went", "chamber", "johanan", and "eliashib". It is saying that the verse draws attention to "ezra" and "rose", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "Then arose Ezra and made the chief..." into verse 7's "And they made proclamation throughout Judah and...", so "ezra" and "rose" 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 "ezra" and "rose" with trust shaped by these words, not by a vague optimism outside the passage.
