Tubig at langis, ang katayuan nati’y yan ang kawangis
Pilitin mang magsama’y may mahahapis
Ganyang-ganyan tayong dalawa
Ang panuntunan’y magkaiba
Langis at tubig, ‘di mapagsama ng tunay mang pag-ibig
Hinanakit ang s’yang lagging mananaig
Mahal na mahal man kita
May mahal ka naming iba
Chorus:
Tubig at langis
Idarang man sa init. ‘di rin tatamis
Dahil ang halo’y luha’t paghihinagpis
Ang kirot ay di maalis kung labis
Bakit nanaig ang dusa sa ligaya sa’ting daigdig?
May dasal ba akong hindi n’yan narinig?
Papel natin sa pag-ibig
Ako’y langis, ika’y tubig
Repeat Chorus:
Bakit nanaig ang dusa sa ligaya sa’ting daigdig?
May dasal ba akong hindi n’yan narinig?
Papel natin sap ag-ibig
Ako’y langis, ika’y tubig
Ako’y langis, ika’y tubig
