Passage
and they enter into a covenant to seek Jehovah, God of their fathers, with all their heart, and with all their soul,
and they enter into a covenant to seek Jehovah, God of their fathers, with all their heart, and with all their soul,
2 Chronicles 15:10 And they are gathered to Jerusalem in the third month of the fifteenth year of the reign of Asa,
2 Chronicles 15:11 and sacrifice to Jehovah on that day from the spoil they have brought in--oxen seven hundred, and sheep seven thousand,
2 Chronicles 15:12 and they enter into a covenant to seek Jehovah, God of their fathers, with all their heart, and with all their soul,
2 Chronicles 15:13 and every one who doth not seek for Jehovah, God of Israel, is put to death, from small unto great, from man unto woman.
2 Chronicles 15:14 And they swear to Jehovah with a loud voice, and with shouting, and with trumpets, and with cornets,
The verse centers on "enter", "covenant", "seek", "jehovah", "fathers", "heart", and "soul". It is saying that the verse draws attention to "enter" and "covenant", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "and sacrifice to Jehovah on that day..." into verse 13's "and every one who doth not seek...", so "enter" and "covenant" 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 "enter" and "covenant" with trust shaped by these words, not by a vague optimism outside the passage.
