OET interlinear 1 KI 15:14

uW Translation Notes:

Note 1 topic: writing-pronouns

וְ⁠הַ⁠בָּמ֖וֹת לֹא־סָ֑רוּ

(Some words not found in UHB: and,the_high,places not taken_away only heart_of ʼĀşāʼ it_became true with YHWH all/each/any/every his/its=days )

The author is using the pronoun they in a general sense, not to refer to specific people. Use an expression for this that would be natural in your language. Alternate translation: [But no one removed the high places] or [But the high places were not removed]

Note 2 topic: figures-of-speech / metaphor

לְבַב־אָסָ֗א הָיָ֥ה שָׁלֵ֛ם עִם־יְהוָ֖ה

heart_of ʼĀşāʼ it_became (Some words not found in UHB: and,the_high,places not taken_away only heart_of ʼĀşāʼ it_became true with YHWH all/each/any/every his/its=days )

See how you translated the similar expression in 8:61. Alternate translation: [Asa was completely devoted to Yahweh]

Note 3 topic: figures-of-speech / metonymy

כָּל־יָמָֽי⁠ו

(Some words not found in UHB: and,the_high,places not taken_away only heart_of ʼĀşāʼ it_became true with YHWH all/each/any/every his/its=days )

The author is using the term days to refer to a specific time, the lifetime of Asa. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [throughout his lifetime]
