Holl amrantau'r sêr ddywedant,
Ar hyd y nos.
Dyma'r ffordd i fro gogoniant,
Ar hyd y nos;
Golau arall yw tywyllwch,
I arddangos gwir brydferthwch;
Teulu'r nefoedd mewn tawelwch,
Ar hyd y nos.

O! Mor siriol gwena'r 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.
