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.

In Genesis 23:2, mourn relates to good or evil, and weep to truth or falsity. (Doctrine Regarding Sacred Scripture 84)

In Revelation 18:8, this symbolizes an inner anguish owing to being in a state of poverty and wretchedness instead of wealth. (Apocalypse Revealed 764, 765)
