Passage
Then in the midst of the assembly the Spirit of Yahweh came upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, the Levite of the sons of Asaph;
Then in the midst of the assembly the Spirit of Yahweh came upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, the Levite of the sons of Asaph;
2 Chronicles 20:12 O our God, will You not judge them? For we are powerless before this great multitude who are coming against us; and we do not know what we should do, but our eyes are on You.”
2 Chronicles 20:13 Now all Judah was standing before Yahweh, with their little ones, their wives, and their children.
2 Chronicles 20:14 Then in the midst of the assembly the Spirit of Yahweh came upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, the Levite of the sons of Asaph;
2 Chronicles 20:15 and he said, “Pay attention, all Judah and the inhabitants of Jerusalem and King Jehoshaphat: thus says Yahweh to you, ‘Do not fear or be dismayed because of this great multitude, for the battle is not yours but God’s.
2 Chronicles 20:16 Tomorrow go down against them. Behold, they will come up by the ascent of Ziz, and you will find them at the end of the valley in front of the wilderness of Jeruel.
The verse centers on "Spirit", "midst", "assembly", "yahweh", "came", "upon", "jahaziel", and "zechariah". It is saying that the verse draws attention to "Spirit" and "midst", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Now all Judah was standing before Yahweh..." into verse 15's "and he said Pay attention all Judah...", so "Spirit" and "midst" belong inside that flow. In 2 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "midst" with trust shaped by these words, not by a vague optimism outside the passage.
