'Walk' in the Bible

But Jehu took no heed to walk in the law of Jehovah the God of Israel with all his heart; he departed not from the sins of Jeroboam, who made Israel to sin.

And the king stood on the dais, and made a covenant before Jehovah, to walk after Jehovah, and to keep his commandments and his testimonies and his statutes with all his heart, and with all his soul, to establish the words of this covenant that are written in this book. And all the people stood to the covenant.
