Where does the Torah speak about washing the hands?
Washing the hands and feet is referred to many times in the Bible.
There was a washing basin in the Tabernacle where the priests washed
their hands and feet before entering (Ex.30:18-21). Washing the
hands is specifically mentioned in Deut.21:6 (see also Lev. 15:11) and in Psalms 26:6
An entire tractate of the Mishnah (Yadayim) is devoted to impurity
of the hands. Washing the hands before eating is discussed in the
Mishnah in (for example) Berachos Ch.8. The laws about washing the hands on arising are codified in Shulchan Aruch Orach Chayim Sec.4; the laws about washing the hands before eating, in Sec.158ff.
