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 31:8
8
Behold, I will bring them from the north country, and gather them from the uttermost parts of the earth, [and] with them the blind and the lame, the woman with child and her who travails with child together: a great company shall they return here.
