Passage
And they swore to the Lord with a loud voice with joyful shouting, and with sound of trumpet, and sound of cornets,
And they swore to the Lord with a loud voice with joyful shouting, and with sound of trumpet, and sound of cornets,
2 Chronicles 15:12 And he went in to confirm as usual the covenant, that they should seek the Lord the God of their fathers with all their heart, and with all their soul.
2 Chronicles 15:13 And if any one, said he, seek not the Lord the God of Israel, let him die, whether little or great, man or woman.
2 Chronicles 15:14 And they swore to the Lord with a loud voice with joyful shouting, and with sound of trumpet, and sound of cornets,
2 Chronicles 15:15 All that were in Juda with a curse: for with all their heart they swore, and with all their will they sought him, and they found him, and the Lord gave them rest round about.
2 Chronicles 15:16 Moreover Maacha the mother of king Asa he deposed from the royal authority, because she had made in a grove an idol of Priapus: and he entirely destroyed it, and breaking it into pieces, burnt it at the torrent Cedron.
The verse centers on "swore", "lord", "loud", "voice", "joyful", "shouting", "sound", and "trumpet". It is saying that the verse draws attention to "swore" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "And if any one said he seek..." into verse 15's "All that were in Juda with a...", so "swore" and "lord" 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 "swore" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
