Isaiah 55:12

For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands.

For ye shall go with joy - from the various countries in which ye (the Jews) are scattered, to your own land ().

And be led forth with peace - by Messiah, your "Leader" (; ; Micah 2:12).

The mountains and the hills shall break forth before you into singing, and all the trees - images justly used to express the seeming sympathy of nature with the joy of God's people. For when sin is removed the natural world shall be delivered from 'vanity,' and be renewed, so as to be in unison with the regenerated moral world (; ; Romans 8:19).
