They won't pour out wine offerings to Yahweh, Neither will they be pleasing to him. Their sacrifices will be to them like the bread of mourners; All who eat of it will be polluted; For their bread will be for their appetite. It will not come into the house of Yahweh.
"Bread of mourners ..."  This is an ominous expression.  The bread of mourners was the bread eaten during funeral celebrations, during which times all who entered the house of the dead were considered to be unclean. All Israel is thus designated a "house of the dead," and a scene of mourning.
