Atharva Veda 1.25: A prayer to fever, as a charm against his attacks

When Agni blazed when he had pierced the Waters, whereat the Law-observers paid him homage, There, men assever, was thy loftiest birthplace: O Fever, yield-ing to our prayer avoid us.

If thou be fiery glow, or inflammation, or if thy birthplace call for chips of fuel, Rack is thy name, God of the sickly yellow! O Fever, yielding to our prayer avoid us.

Be thou distress, or agonizing torment, be thou the son King Varuna hath begotten, Rack isthy name, God of the sickly yellow! O Fever, yielding to our prayer avoid us.

I offer homage to the chilly Fever, to his fierce burning glow I offer homage.
Be adoration paid to Fever coming each other day, the third, of two days running.
