By day the Lord went ahead of them in a pillar of cloud…and by night in a pillar of fire.@Exodus 13:21
John Hughes (1873–1932)

Will­iam Will­iams, Hal­le­lu­iah (Bris­tol, Eng­land: 1745) (Arglwydd, arwain trwy’r anialwch). Translated from Welsh to Eng­lish by Pe­ter Will­iams, Hymns on Various Subjects (Car­mar­then, Wales: 1771); Will­iams published another Eng­lish translation in Lady Hunt­ing­don’s Collection, circa 1772. This hymn was sung at the wedding of Br­itain’s Prince William & Cath­er­ine Mid­dle­ton in West­min­ster Abbey, Lon­don, April 29, 2011.

Cwm Rhon­dda John Hughes, 1907 (🔊 pdf nwc). Hughes wrote this tune in Ton­teg (near Pon­ty­pridd), Wales, to commemorate a music festival held in nearby Ca­pel Rhon­dda, Hop­kins­town. It was first performed November 1 that year to Welsh words by Ann Griff­iths; in the early days it was simply known as Rhon­dda, but within a year he changed the name to Cwm Rhon­dda, used Pe­ter Will­iams’ translation, and the rest is history. Alternate tunes (some use slightly different endings to the lyrics):

William Williams (1717–1791)

Guide me, O Thou great Jehovah,
[or Guide me, O Thou great Redeemer…]
Pilgrim through this barren land.
I am weak, but Thou art mighty;
Hold me with Thy powerful hand.
Bread of Heaven, Bread of Heaven,
Feed me till I want no more;
Feed me till I want no more.

Feed me with the heavenly manna,
In this barren wilderness;
Be my sword, and shield, and banner—
Be my robe of righteousness.
Fight and conquer, fight and conquer
All my foes by sovereign grace,
All my foes by sovereign grace.*

Open now the crystal fountain,
Whence the healing stream doth flow;
Let the fire and cloudy pillar
Lead me all my journey through.
Strong deliverer, strong deliverer,
Be Thou still my strength and shield;
Be Thou still my strength and shield.

Lord, I trust Thy mighty power,
Wondrous are Thy works of old;
Thou deliver’st Thine from thralldom,
Who for naught themselves had sold:
Thou didst conquer, Thou didst conquer,
Sin, and Satan and the grave,
Sin, and Satan and the grave.

When I tread the verge of Jordan,
Bid my anxious fears subside;
Death of deaths, and hell’s destruction,
Land me safe on Canaan’s side.
Songs of praises, songs of praises,
I will ever give to Thee;
I will ever give to Thee.

Musing on my habitation,
Musing on my heav’nly home,
Fills my soul with holy longings:
Come, my Jesus, quickly come;
Vanity is all I see;
Lord, I long to be with Thee!
Lord, I long to be with Thee!

*Probably a later addition. First known publication of this stanza was in 1810.
