Rig Veda
भूय॑सा व॒स्नम॑चर॒त्कनी॒योऽवि॑क्रीतो अकानिषं॒ पुन॒र्यन् । स भूय॑सा॒ कनी॑यो॒ नारि॑रेचीद्दी॒ना दक्षा॒ वि दु॑हन्ति॒ प्र वा॒णम् ॥ भूयसा वस्नमचरत्कनीयोऽविक्रीतो अकानिषं पुनर्यन् । स भूयसा कनीयो नारिरेचीद्दीना दक्षा वि दुहन्ति प्र वाणम् ॥
A man has realized a small price for an article of great value, and again coming (to the buyer he says) this has not been sold; I require the full price; but he does not recover a small price by a large (equivalent); whether helpless or clever they adhere to their bargain.
