'Devoted' in the Bible

Now let your heart be completely devoted to the LORD our God, to live according to his statutes and to keep his commands, as we are doing today."

because as Solomon grew older, his wives turned his affections away after other gods, and his heart was not fully as devoted to the LORD his God as his father David's heart had been.

He practiced the same sins that his father committed before he was born. Unlike his ancestor David, his heart never became devoted to the LORD his God.
