'Perfect' in the Bible

and that your heart may be perfect with Jehovah our God, to walk in his statutes and to keep his commandments, as at this day.

And it came to pass when Solomon was old, that his wives turned away his heart after other gods; and his heart was not perfect with Jehovah his God, as the heart of David his father.

And he walked in all the sins of his father, which he had done before him; and his heart was not perfect with Jehovah his God, as the heart of David his father.

But the high places were not removed; only, Asa's heart was perfect with Jehovah all his days.
