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.
Leviticus 15:10-12

Whoever touches anything that was under him shall be unclean until the evening. He who carries those things shall wash his clothes, and bathe himself in water, and be unclean until the evening.
11
"'Whoever he who has the discharge touches, without having rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the evening.
12
"'The earthen vessel, which he who has the discharge touches, shall be broken; and every vessel of wood shall be rinsed in water.
