Sleep my child and peace attend thee All through the night Guardian angels God will send thee All through the night 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 All through the night While the weary world is sleeping All through the night O'er thy spirit gently stealing Visions of delight revealing Breathes a pure and holy feeling All through the night
