Ludwig: Die wissen um den grossen raum, alle götter truges bar, mit den Marut, Agni, kom.
Note 1. The sky or welkin (rágas) is the proper abode of the Maruts, and 'they who know of' means simply 'they who dwell' in the great sky. The Vedic poets distinguish commonly between the three worlds, the earth, prithivî´, f., or pâ´rthiva, n.; the sky, rágas; and the heaven, dyú: see I, 6, 9, note 1. The phrase maháh rágasah occurs I, 6, 10; 168, 6, &c. Sâyana takes rágas for water or rain: see on this my article in Kuhn's Zeitschrift, vol. xii, p. 28. In some passages rágas means 'darkness,' and might be identified with the Greek Ἔρεβος; Ath. Veda VIII, 2, 1. pâráyâmi tvâ rágasa út tvâ mrityór apîparam, 'I bring thee out of darkness, out of death I brought thee.' The identification of rágas with ἔρεβος (Leo Meyer, in Kuhn's Zeitschrift, vol. vi, p. 19) must however remain doubtful, until stronger evidence has been brought forward in support of a Greek β representing a Sanskrit g, even in the middle of a word. See my article in Kuhn's Zeitschrift, vol. xv, p. 215; Curtius. Grundzüge (fifth edition), p. 480.
Note 2. The appellation Vísve devâ´h, all gods together, or, more properly, host-gods, is often applied to the Maruts; cf. I, 23, 8; 10. Benfey connects this line with the preceding verse, considering Vísve devâ´h, it seems, inappropriate as an epithet of the Maruts.
Note 3. On adrúh, without guile or deceit, without hatred, see Kuhn's excellent article, Zeitschrift für die Vergleichende Sprachforschung, vol. i, pp. 179, 193. Adrúh is applied to the Maruts again in VIII, 46, 4, though in connection with other gods. It is applied to the Visve Devas, RV. I, 3, 9; IX, 102, 5: the Âdityas, RV. VIII, 19, 34; 67, 13: the Rudras, RV. IX, 73, 7: to Heaven and Earth, RV. II, 41, 21; III, 56, 1; IV, 56, 2; VII, 66, 18: to Mitra and Varuna, RV. V, 68, 4: to Agni, RV. VI, 15, 7; VIII, 44, 10. The form adhrúk occurs in the sixth Mandala only.
Verse 4.
Wilson: Who are fierce, and send down rain, and are unsurpassed in strength: come, Agni, with the Maruts.
Benfey: Die schrecklich-unbesiegbaren, die mächtiglich Licht angefacht—Mit diesen Marut’s, Agni! komm!
Ludwig: Die singen, die gewaltigen, ihr lied unangegriffen durch (ihre) kraft, mit den Marut, Agni, kom.
