Manusmriti

siva.sh/manusmriti/2/158

यथा षण्ढोऽफलः स्त्रीषु यथा गौर्गवि चाफला । यथा चाज्ञेऽफलं दानं तथा विप्रोऽनृचोऽफलः ॥ १५८ ॥

sanskrit

As a eunuch is unproductive with women, as a cow with a cow is unprolific, and as a gift made to an ignorant man yields no reward, even so is a Brahmana useless, who (does) not (know) the Rikas.
