And they rose early in the morning and went out to the wilderness of Tekoa; and when they went out, Jehoshaphat stood and said, “Listen to me, O Judah and inhabitants of Jerusalem, establish your faith in Yahweh your God and you will be established. Establish your faith in His prophets and succeed.”
2 Chronicles 20:18 So Jehoshaphat bowed his head with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before Yahweh, worshiping Yahweh.
2 Chronicles 20:19 Then the Levites, from the sons of the Kohathites and of the sons of the Korahites, rose up to praise Yahweh, the God of Israel, with a very loud voice.
2 Chronicles 20:20 And they rose early in the morning and went out to the wilderness of Tekoa; and when they went out, Jehoshaphat stood and said, “Listen to me, O Judah and inhabitants of Jerusalem, establish your faith in Yahweh your God and you will be established.

2 Chronicles 20:21 When he had taken counsel with the people, he caused those who sang to Yahweh and those who praised Him to stand in holy attire, as they went out before the army, saying, “Give thanks to Yahweh, for His lovingkindness endures forever.”
2 Chronicles 20:22 When they began singing for joy and praising, Yahweh set ambushes against the sons of Ammon, Moab, and Mount Seir, who had come against Judah; so they were defeated.
The verse centers on "faith", "rose", "early", "morning", "went", "wilderness", "tekoa", and "jehoshaphat". It is saying that the verse draws attention to "faith" and "rose", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "Then the Levites from the sons of..." into verse 21's "When he had taken counsel with the...", so "faith" and "rose" 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 "faith" and "rose" with trust shaped by these words, not by a vague optimism outside the passage.
