I became familiar with this carol a year ago.  It is apparently sung commonly in the New England region during the Christmas season.  The lyrics are provide below the video.

1. The tree of life my soul hath seen,
Laden with fruit and always green:
The trees of nature fruitless be
Compared with Christ the apple tree.

2. His beauty doth all things excel:
By faith I know, but ne’er can tell
The glory which I now can see
In Jesus Christ the apple tree.

3. For happiness I long have sought,
And pleasure dearly I have bought:
I missed of all; but now I see
‘Tis found in Christ the apple tree.

4. I’m weary with my former toil,
Here I will sit and rest awhile:
Under the shadow I will be,
Of Jesus Christ the apple tree.

5. This fruit doth make my soul to thrive,
It keeps my dying faith alive;
Which makes my soul in haste to be
With Jesus Christ the apple tree.

I heard this delightful little carol for the first time this week.  Beneath the video are the lyrics.

Girls and boys – Leave your toys – Make no noise
Kneel at his crib and worship him
At thy shrine – Child divine – We are thine
Our Savior’s here

Chorus:
“Hallelujah” the church bells ring
“Hallelujah” the angels sing
“Hallelujah” from everything
All must draw near

On that day – Far away – Jesus lay
Angels were watching ’round his head
Holy Child – Mother mild – Undefiled
We sing thy praise

repeat 3 lines of chorus
Our hearts we raise

Shepherds came – At the fame – Of thy name
Angels their guide to Bethlehem
In that place – Filled with grace – Saw thy face
Stood at they door

repeat 3 lines of chorus
Love evermore

Wise men too – Haste to do – Homage new
Gold, myrrh and frankincence they bring
As ’twas said – Starlight led – To thy bed
Bending their knee

repeat 3 lines of chorus
Worshipping thee

Oh, that we – All might be – Good as he
Spotless, with God in unity
Savior dear – Ever near – With us here
Since life began

repeat 3 lines of chorus
God head made man

Cherubim – Seraphim – Worship him
Sun, moon and stars proclaim his power
Every day – On our way – we shall say
Hallelujah

repeat 3 lines of chorus
Hallelujah

This is without a doubt one of my most favorite Christmas hymns.

This is one of my favorite Christmas hymns.

I also enjoy the British observance of the men singing a stanza and the women another.  This adds such a richness to the vocalization that we miss in many churches today.

We typically sing the first half of each stanza, and the refrain is the last half of the first stanza.  We miss the richness of the halves of the stanzas that we do not sing, especially the second half of the second stanza, which answers the questions what Child is this, and why did He come?
