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 3:8-9
8
I saw, when, for this very cause that backsliding Israel had committed adultery, I had put her away and given her a bill of divorce, yet treacherous Judah, her sister, didn't fear; but she also went and played the prostitute.
9
It happened through the lightness of her prostitution, that the land was polluted, and she committed adultery with stones and with stocks.
