שולחן ערוך · אורח חיים

Concise summary:

ב׳ seifim: one who has relieved himself (העושה צרכיו) and wishes to eat bread faces two duties of washing that converge: the washing of the hands on account of the toilet (over which he says אשר יצר) and the נטילת ידים of the meal (over which he says על נטילת ידים). The Mehaber settles the order of the berakhot according to whether he washes twice or once, and the timing of the netila blessing; then (seif ב׳) the conduct when many are seated — the greatest washes first, but the Rosh would wash last so as not to interrupt between the netila and the bread (תכף לנטילה סעודה).
