Srimad Bhagavatam Canto 10, Chapter 20, Text 24

 SB 10.20.24

vyamuñcan vayubhir nunna
 bhutebhyas camrtam ghanah
yathasiso vis-patayah
 kale kale dvijeritah
The clouds, impelled by the winds, released their nectarean water for the benefit of all living beings, just as kings, instructed by their brahmana priests, dispense charity to the citizens.
Srila Prabhupada comments: “In the rainy season, the clouds, tossed by the wind, deliver water, which is welcomed like nectar. When the Vedic followers, the brahmanas, inspire rich men like kings and the wealthy mercantile community to give charity in the performance of great sacrifices, the distribution of such wealth is also nectarean. The four sections of human society, namely the brahmanas, the ksatriyas, the vaisyas and the sudras, are meant to live peacefully in a cooperative mood; this is possible when they are guided by expert Vedic brahmanas who perform sacrifices and distribute wealth equally.”
