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 16:27
27
Behold, therefore I have stretched out my hand over thee, and have diminished thy ordinary food, and delivered thee to the will of them that hate thee, the daughters of the Philistines, who are ashamed of thy lewd way.
