2 Chronicles 15:8 And when Asa heard these wordes, and the prophesie of Obed the Prophet, he was encouraged, and tooke away the abominations out of all the lande of Iudah, and Beniamin, and out of the cities which he had taken of mount Ephraim, and he renued the altar of the Lord, that was before the porche of the Lord.

2 Chronicles 15:10 So they assembled to Ierusalem in the third moneth, in the fifteenth yere of the reigne of Asa.
The verse centers on "heard", "wordes", "prophesie", "obed", "prophet", "encouraged", "tooke", and "away". It is saying that the verse draws attention to "heard" and "wordes", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "Be ye strong therefore and let not..." into verse 9's "And he gathered all Iudah and Beniamin...", so "heard" and "wordes" 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 "heard" and "wordes" with trust shaped by these words, not by a vague optimism outside the passage.
