In Pharr §38, the exercise is to translate from Greek this sentence:
di=oj e9khbo/loj au0to\s a0ei/dei, a0ll' ou0x a9nda/nei a0/lloisi qeoi=si qumw|=. Additionally, the student is pointed to §996 and §1009.
Mr. Annis's kindly provided answer key indicates that this could be translated as "The divine free-shooter himself sings, but it doesn't please the other gods in their souls."
My question revolves around translating qumw|= as "in their souls." Isn't the form given singular?
