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.
Isaiah 3:6-7
6
Indeed a man shall take hold of his brother in the house of his father, saying, "You have clothing, you be our ruler, and let this ruin be under your hand."
7
In that day he will cry out, saying, "I will not be a healer; for in my house is neither bread nor clothing. You shall not make me ruler of the people."
