I have a book with a couple hundred hymns by Isaac Watts, and I found this one that goes along with Palm Sunday.  We are planning to sing it this Sunday using the familiar tune to O For A Thousand Tongues To Sing (both hymns share the same meter and the music fits well).  Read the words and notice their theological depth in reference to the person of Christ that leads to the call to praise him.

Hosannah To Christ
Isaac Watts

Hosannah to the royal Son
Of David’s ancient line!
His natures two, his person one,
Mysterious and divine.

The root of David here, we find,
And offspring is the same:
Eternity and time are join’d
In our Immanuel’s name

Bless’d he that comes to wretched men
With peaceful news from heav’n!
Hosannahs of the highest strain
To Christ the Lord be giv’n!

Let mortals ne’er refuse to take
The hosannah on their tongues,
Lest rocks and stones should rise and break
Their silence into songs.
