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.
Zechariah 14:17-18
17
It will be, that whoever of all the families of the earth doesn't go up to Jerusalem to worship the King, Yahweh of Armies, on them there will be no rain.
18
If the family of Egypt doesn't go up, and doesn't come, neither will it rain on them. This will be the plague with which Yahweh will strike the nations that don't go up to keep the feast of tents.
