'Walk' in the Bible

But Jehu was not careful to walk in the law of the Lord, the God of Israel, with all his heart; he did not depart from the sins of Jeroboam, which he made Israel sin.

So he forsook the Lord, the God of his fathers, and did not walk in the way of the Lord.

The king stood by the pillar and made a covenant before the Lord, to walk after the Lord, and to keep His commandments and His testimonies and His statutes with all his heart and all his soul, to carry out the words of this covenant that were written in this book. And all the people entered into the covenant.
