Sleep my child and peace attend thee, Guardian angels God will send thee, Soft the drowsy hours are creeping Hill and vale in slumber sleeping, I my loved ones' watch am keeping, All through the night. O mor siriol, gwena seren Ar hyd y nos I oleuo'i chwaer ddaearen Ar hyd y nos. Nos yw henaint pan ddaw cystudd Ond i harddu dyn a'i hwyrddydd Rhown ein golau gwan i'n gilydd Ar hyd y nos. While the moon her watch is keeping While the weary world is sleeping O'er thy spirit gently stealing Visions of delight revealing Breathes a pure and holy feeling All through the night.
