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.
Jeremiah 2:26-27
26
As the thief is ashamed when he is found, so is the house of Israel ashamed; they, their kings, their princes, and their priests, and their prophets;
27
who tell wood, 'You are my father;' and a stone, 'You have brought me out:' for they have turned their back to me, and not their face; but in the time of their trouble they will say, 'Arise, and save us.'
