य इ॑न्द्राग्नी सु॒तेषु॑ वां॒ स्तव॒त्तेष्वृ॑तावृधा । जो॒ष॒वा॒कं वद॑तः पज्रहोषिणा॒ न दे॑वा भ॒सथ॑श्च॒न ॥
य इन्द्राग्नी सुतेषु वां स्तवत्तेष्वृतावृधा । जोषवाकं वदतः पज्रहोषिणा न देवा भसथश्चन ॥
ya indrāgnī suteṣu vāṃ stavat teṣv ṛtāvṛdhā | joṣavākaṃ vadataḥ pajrahoṣiṇā na devā bhasathaś cana ||

English translation:

“Divine Indra and Agni, augmenters of sacrifice by whom the acclamation (of praise) is received, you partake not of the (Soma) of him who, when the libation is effused, praises you (improperly), uttering unacceptable eulogies.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Praises you improperly: yo vam stavat, he who may praise you badly, kutsitam stūyat; uttering unacceptable eulogies: joṣavākam vadataḥ: prītihetutvena kartavyam svay aprītikaram vacam, speech to be uttered with the design of gaining affection, but of itself producing disaffection or dislike; so, in Nirukta 5.22: ya indragnī suteṣu vām someṣu stauti teṣu na tasya aśnīthaḥ, of him who praises you two, Agni and Indra, when the Soma juices are effused you do not eat (the offering); the Nirukta has: you eat, omitting the negative;

Joṣavākam: avijñatanāmadheyam joṣayitavyam bhavati, that being of unknown name is to be propitiated; yo ayam joṣavākam vadati viañjapaḥ na tasya aśnīthaḥ, this person n who utters, joṣavākam, repeating incessantly, or silently, propitiatory prayer of various objects, of that man, you two do not eat the offering
