Atharvaveda 4.15

Let the directions, full of mist (nábhasvant), fly up together; let clouds, wind-hurried, come together; let the lowing [cows] of the resounding misty great bull, the waters, gratify the earth.

Let the mighty (taviṣá), liberal (sudā́nu) ones cause to behold together; let the juices (rása) of the waters attach themselves (sac) to the herbs; let gushes (sárga) of rain gladden (mahay-) the earth; let herbs of all forms be born here and there (pṛ́thak).

Do thou make the singers (gā́yant) to behold together the mists; let rushes (véga) of waters rush (vij) up here and there; let gushes of rain gladden the earth; let plants of all forms be born here and there.

Let the troops of Maruts sing unto thee, O Parjanya, noisy here and there; let gushes of raining rain rain along the earth.

Send up, O Maruts, from the ocean; brilliant [is] the song; ye make the mist fly up; let the lowing [cows] of the resounding misty great bull, the waters, gratify the earth.

Roar on, thunder, excite (ard) the water-holder; anoint the earth, O Parjanya, with milk; by thee poured out, let abundant rain come; let him of lean kine, seeking refuge, go home.

Let the liberal ones favor (sam-av) you, also the fountains, great serpents (ajagará); let the clouds, started forward by the Maruts, rain along the earth.

Let it lighten to every region (ā́çā); let the winds blow to (from?) every quarter; let the clouds, started forward by the Maruts, come together along the earth.
Ppp. has in d varṣantu, as our text in the preceding verse. The comm. also points out the possibility of taking diçás as either accus. pl. or abl. sing. The Anukr. somehow omits to define the metrical character of this verse and of vs. 14.

Waters, lightning, cloud, rain—let the liberal ones favor you, also the fountains, great serpents; let the clouds, started forward by the Maruts, show favor (pra-av) along the earth.
Ppp. begins with vātas instead of āpas, and omits (as in 7 a) vas in b; and, for the last two pādas, it reads prā pyāyasva pra pitṛsva saṁ bhūmiṁ payasā sṛja. The comm. again takes sudānavas as vocative, and makes the elements mentioned in a subjects of sam avantu; in d he reads plāvantu but regards it as for prā ’vantu ⌊parallel with palāyate etc. (W's Gram. §1087 c), for which he cites Pāṇini viii. 2. 19⌋.

Agni, who, in unison with the waters' selves (tanū́), hath become overlord of the herbs—let him, Jātavedas, win (van) for us rain, breath for [our] progeny, amṛ́ta out of the sky.
The comm. paraphrases amṛtam with amṛtatvaprāpakam. The Anukr. duly notes the redundant syllable in d.

May Prajāpati from the sea, the ocean, sending waters, excite the water-holder; let the seed of the stallion (vṛ́ṣan áçva) be filled up; come hitherward with that thunder,—
To this verse really belongs the first pāda of our vs. 12, as the sense plainly shows, as well as its association in RV. (v. 83. 6 b, c, d) with the two closing pādas here. ⌊Cf. Lanman, Reader, p. 370; misdivision as between hymns.⌋ But the mss., the Anukr., the comm., and both editions, end vs. 11 with é ’hi. RV. reads in our c pinvata for pyāyatām, and dhā́rās for rétas. Ppp. combines in b āp’ īrayann, and begins c with prā py-. The comm. gives viṣṭos instead of vṛṣṇas in c, and explains both it and salilād in a by vyāpanaçīla, which is one of his standing glosses for obscure words; ardayāti he paraphrases with raçmibhir ādānena pīḑayatu, and udadhim simply by jaladhim. This verse is as much bhurij as vs. 10, unless we combine ā́pe ”ráyan in b. ⌊For -núnéhi, see Prāt. iii. 38, note.⌋

Pouring down waters, our Asura father.
Let the gurgles of the waters puff, O Varuṇa; let down the descending waters; let the speckled-armed frogs croak (vad) along the water-courses (íriṇa).

Having lain for a year, [like] Brahmans performing a vow, the frogs have spoken forth a voice quickened by Parjanya.

Speak forth unto [it], O she-frog; speak to the rain, O tādurī; swim in the midst of the pool, spreading thy four feet.

O khaṇvakhā! O khāimakhā! in the middle, O tadurī! win ye rain, O Fathers; seek the favor (mánas) of the Maruts.

The great vessel (kóça) do thou draw up (ud-ac); pour on; let there be lightnings; let the wind blow; let them extend the sacrifice, being manifoldly let loose; let the herbs become full of delight.
