Then all the men of Juda, and Benjamin gathered themselves together to Jerusalem within three days, in the ninth month, the twentieth day of the month: and all the people sat in the street of the house of God, trembling because of the sin, and the rain.
Ezra 10:7 And proclamation was made in Juda and Jerusalem to all the children of the captivity, that they should assemble together into Jerusalem.
Ezra 10:8 And that whosoever would not come within three days, according to the counsel of the princes and the ancients, all his substance should be taken away, and he should be cast out of the company of them that were returned from captivity.
Ezra 10:9 Then all the men of Juda, and Benjamin gathered themselves together to Jerusalem within three days, in the ninth month, the twentieth day of the month: and all the people sat in the street of the house of God, trembling because of the sin, and the rain.
Ezra 10:10 And Esdras the priest stood up, and said to them: You have transgressed, and taken strange wives, to add to the sins of Israel.
Ezra 10:11 And now make confession to the Lord the God of your fathers, and do his pleasure, and separate yourselves from the people of the land, and from your strange wives.
The verse centers on "juda", "benjamin", "gathered", "themselves", "together", "jerusalem", "within", and "three". It is saying that the verse draws attention to "juda" and "benjamin", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "And that whosoever would not come within..." into verse 10's "And Esdras the priest stood up and...", so "juda" and "benjamin" 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 "juda" and "benjamin" with trust shaped by these words, not by a vague optimism outside the passage.
