Ye te bhikkhū therā rattaññū cirapabbajitā saṅghapitaro saṅghapariṇāyakā te atirekapūjāya pūjetā hoti.

It’s when a mendicant knows form, is skilled in characteristics, picks out flies’ eggs, dresses wounds, spreads smoke, knows the ford, knows satisfaction, knows the trail, is skilled in ranges, doesn’t milk dry, and shows extra respect to senior mendicants of long standing, long gone forth, fathers and leaders of the Saṅgha.
