'Rhwn sy'n peri'r mellt i hedeg

He who darts the wingèd lightning, --

Walks upon the foaming wave, --

Send forth arrows of conviction

Here, -- exert his power to save:

Burst the bars of Satan's prison:

Snatch the firebrand from the flame,

Fill the doubting with assurance:

Teach the dumb to sing His name!
