'Walking' in the Bible

He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God.

At the end of 12 months, as he was walking on the roof of the royal palace in Babylon,

Now, I, Nebuchadnezzar, am praising and exalting and honouring the King of the heavens, for all His works are truth, and His paths judgment, and those walking in pride He is able to humble.'

and have not obeyed the voice of the LORD our God by walking in his laws that he gave us through his servants the prophets.
