'Perfect' in the Bible

"Let your heart therefore be perfect with Yahweh our God, to walk in his statutes, and to keep his commandments, as at this day."

For it happened, when Solomon was old, that his wives turned away his heart after other gods; and his heart was not perfect with Yahweh his God, as was the heart of David his father.

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

But the high places were not taken away: nevertheless the heart of Asa was perfect with Yahweh all his days.
