Viṣṇusahasranāmastotram

Verse 214

इति महाभारते कर्मकाण्डे ।सर्वाण्येतानि नामानि परस्य ब्रह्मणोऽनघ ।एवमेतानि नामानि देवदेवस्य कीर्तयेत् ॥

In plain words

So it stands in the Mahābhārata, in the portion on ritual action. All these names, faultless one, belong to the supreme Brahman; and just so one should say them aloud — the names of the God of gods.

Close to the Sanskrit

Thus in the Mahābhārata, in the section on ritual action. All these names are of the supreme Brahman, O faultless one; thus one should proclaim these names of the God of gods.
