Be Ye Joyful, Earth and Sky

Be ye joyful, earth and sky,
Hallelujah!
Unto us God’s Son came nigh,
Hallelujah!

Refrain

He for our salvation
Left God’s habitation,
Yes, He left God’s habitation.

Here the fairest Rose we see,
Hallelujah!
Blooming forth from Jesse’s tree,
Hallelujah!

Refrain

He, the great incarnate Word,
Hallelujah!
Jesus Christ doth help afford,
Hallelujah!
