Not specifically for funerals: this is an anthem, with a general text which is sometimes sung at funerals, presumably because the choir knows it already!
César Franck’s lovely motet, is a setting of a communion text, taken from his 'La Messe Solenelle'.

Panis Angelicus by Cesar Franck (1822 - 1890)
Panis Angelicus fit panis hominum;
Dat panis coelicus figuris terminum:
O res mirabilis! manducat Dominum
Pauper, servus et humilis.

The bread of angels becomes the bread of men
and brings earthly forms to an end.
O marvellous act: a poor man, a slave and a humble man
all eat of the Lord.
