BabylonianTalmud, Brachot 58a

Our Rabbis taught: One who sees a crowd of Israelites, is to say, Blessed is the One who discerns secrets, for their minds are not similar to each other, and their faces are not similar to each other. Ben Zoma once saw a crowd on one of the steps of the Temple Mount. He said, Blessed is the One who discerns secrets, and blessed is the One who has created all these to serve me. For he used to say: What labors the first person had to carry out before he obtained bread to eat! He ploughed, he sowed, he reaped, he bound [the sheaves], he threshed and winnowed and selected the ears, he ground [them], and sifted [the flour], he kneaded and baked, and then at last he ate. But I get up, and find all these things done for me. And how many labors the first person had to carry out before he obtained a garment to wear! He had to shear, wash [the wool], comb it, spin it and weave it, and then at last he obtained a garment to wear; whereas I get up and find all these things done for me. All kinds of craftsmen come early to the door of my house, and I rise in the morning and find all these before me. [Soncino translation] [The standard text reads אומות, which translates as “craftsmen”. Alternate texts read אומנויות, nations, and Rashi explains this is because a single nation cannot provide every person’s need. What one country lacks, the other provides]
