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 3:1-2
1
"They say, 'If a man puts away his wife, and she goes from him, and become another man's, will he return to her again?' Wouldn't that land be greatly polluted? But you have played the prostitute with many lovers; yet return again to me," says Yahweh.
2
"Lift up your eyes to the bare heights, and see! Where have you not been lain with? You have sat for them by the ways, as an Arabian in the wilderness. You have polluted the land with your prostitution and with your wickedness.
