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.
Judges 4:15-16
15
Yahweh confused Sisera, and all his chariots, and all his army, with the edge of the sword before Barak; and Sisera alighted from his chariot, and fled away on his feet.
16
But Barak pursued after the chariots, and after the army, to Harosheth of the Gentiles: and all the army of Sisera fell by the edge of the sword; there was not a man left.
