SB 9.14.5

yada sa deva-guruna
 yacito ’bhiksnaso madat
natyajat tat-krte jajñe
 sura-danava-vigrahah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Although requested again and again by Brhaspati, the spiritual master of the demigods, Soma did not return Tara. This was due to his false pride. Consequently, a fight ensued between the demigods and the demons.
