What does 2 Chronicles 34:28 mean?

Because they have forsaken me, and have burned incense to other gods, that they might provoke me to anger with all the works of their hands; therefore my wrath is poured out on this place, and it will not be quenched.’”’

But to the king of Judah, who sent you to inquire of Yahweh, you shall tell him this, ‘Yahweh, the God of Israel says: “About the words which you have heard,

because your heart was tender, and you humbled yourself before God, when you heard his words against this place, and against its inhabitants, and have humbled yourself before me, and have torn your clothes, and wept before me, I also have heard you,” says Yahweh.

Then the king sent and gathered together all the elders of Judah and Jerusalem.

The king went up to Yahweh’s house, with all the men of Judah and the inhabitants of Jerusalem, the priests, the Levites, and all the people, both great and small; and he read in their hearing all the words of the book of the covenant that was found in Yahweh’s house.

The king stood in his place, and made a covenant before Yahweh, to walk after Yahweh, and to keep his commandments, and his testimonies, and his statutes, with all his heart, and with all his soul, to perform the words of the covenant that were written in this book.
