Śatapatha Brāhmaṇa ("of a hundred paths") 2.3.4.16

2.3.4.16

tadetatsamāhāryaṃ ṣaḍṛcam | tasyopavatī prathamā pratnavatyuttamāvocāma tadyasmādupavatyathāda eva pratnaṃ yāvanto hyeva sanāgre devāstāvanta eva devāstasmādadaḥ pratnaṃ tadime evāntareṇa sarve kāmāste asmā ime saṃjānāne sarvān kāmāntsaṃnamataḥ

This is a hymn of six verses collected (from the Rik); the first of them containing (the word) 'upon,' and the last containing (the word) 'old' (pratna). And this we recited, because she (the earth) is the one that contains the (word) 'upon;' and that which is 'old' doubtless is yonder (sky), for as many gods as there were 'of old,' in the beginning, so many gods there are now, and hence the 'old' means yonder (sky). Now within these two (worlds) all desires are contained; and these two are in accord with each other for his (the sacrificer's) benefit, and concede all his wishes.
