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.
Malachi 1:5-6
5
Your eyes will see, and you will say, "Yahweh is great--even beyond the border of Israel!"
6
"A son honors his father, and a servant his master. If I am a father, then where is my honor? And if I am a master, where is the respect due me? Says Yahweh of Armies to you, priests, who despise my name. You say, 'How have we despised your name?'
