Walk
Walking represents living, and usually means living according to the true things taught to us by the Lord -- to "walk in His ways." When the Lord is pictured walking, it means life itself.
Ezekiel 21:28-29

29
while they see for you false visions, while they divine lies to you, to lay you on the necks of the wicked who are deadly wounded, whose day is come in the time of the iniquity of the end.
