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 16:8-9
8
Now when I passed by you, and looked at you, behold, your time was the time of love; and I spread my skirt over you, and covered your nakedness: yes, I swore to you, and entered into a covenant with you, says the Lord Yahweh, and you became mine.
9
Then washed I you with water; yes, I thoroughly washed away your blood from you, and I anointed you with oil.
