Dhammapada 80 [Khuddaka Nikaya]

6 - Panditavagga, The Wise
5 - Panditasamanera Vatthu

Udakam hi nayanti nettika,
usukara namayanti tejanam;
darum namayanti tacchaka,
attanam damayanti pandita.

80: Farmers (lit., makers of irrigation canals ) channel the water; fletchers straighten the arrow; carpenters work the timber; the Wise tame themselves.
