Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 6.3.7

6.3.7

na ha vā enam mahān devo hinasti / (Zūlagava: brahmatva)

vi. 6. A fifth time he grasped him; he said to him, ‘Why dost thou grasp me?’ He replied, ‘Give me a fifth name, for with four names only I shall not eat food here.’ He answered, ‘Thou art the great god.’ Since the sun is the great god, thereby the great god harms him not, nor his offspring, nor his cattle, nor any one claiming to be his. He who hates him becomes worse, not he who knows thus. His vow is ‘One should not look at him on his rising or on his setting.’
