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 37:25-26
25
They shall dwell in the land that I have given to Jacob my servant, in which your fathers lived; and they shall dwell therein, they, and their children, and their children's children, forever: and David my servant shall be their prince for ever.
26
Moreover I will make a covenant of peace with them; it shall be an everlasting covenant with them; and I will place them, and multiply them, and will set my sanctuary in the midst of them forevermore.
