Bible Verses About Mountains: (Breaking forth into singing,) of exceeding joy

Sing for joy, O heavens, for the LORD has done this; shout aloud, O depths of the earth. Break forth in song, O mountains, you forests and all your trees. For the LORD has redeemed Jacob, and revealed His glory in Israel.

You will indeed go out with joy and be led forth in peace; the mountains and hills will burst into song before you, and all the trees of the field will clap their hands.
