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.

'Hamor, the father of Schechem,' represents the good and truth of the church among the ancients. He also represented life, for life is of good, as doctrine is of truth.
