Atharvaveda 19.9.4

19.9.4

idáṃ yát parameṣṭhínaṃ máno vāṃ bráhmasaṃśitam |
yénaivá sasr̥jé ghoráṃ ténaivá śā́ntir astu naḥ ||4||

Or (?) this mind that is most exalted, sharpened by bráhman, by which is produced what is terrible—by that be there appeasement for us.
All the mss. read in b vām instead of vā, and SPP's text follows them. The comm. makes no mention of either in its exposition of the verse; but its text (so SPP. reports) reads vā, as does ours by emendation.
