Passage
And they sware vnto the Lord with a loude voyce, and with shouting and with trumpets, and with cornets.
And they sware vnto the Lord with a loude voyce, and with shouting and with trumpets, and with cornets.
2 Chronicles 15:12 And they made a couenant to seeke the Lord God of their fathers, with all their heart, and with all their soule.
2 Chronicles 15:13 And whosoeuer will not seeke the Lord God of Israel, shalbe slaine, whether he were small or great, man or woman.
2 Chronicles 15:14 And they sware vnto the Lord with a loude voyce, and with shouting and with trumpets, and with cornets.
2 Chronicles 15:15 And all Iudah reioyced at the othe: for they had sworne vnto the Lord with all their heart, and sought him with a whole desire, and he was founde of them. And the Lord gaue them rest rounde about.
2 Chronicles 15:16 And King Asa deposed Maachah his mother from her regencie, because she had made an idole in a groue: and Asa brake downe her idole, and stamped it, and burnt it at the brooke Kidron.
The verse centers on "sware", "vnto", "lord", "loude", "voyce", "shouting", "trumpets", and "cornets". It is saying that the verse draws attention to "sware" and "vnto", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "And whosoeuer will not seeke the Lord..." into verse 15's "And all Iudah reioyced at the othe...", so "sware" and "vnto" 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 "sware" and "vnto" with trust shaped by these words, not by a vague optimism outside the passage.
