Their sacrifices will be to them like mourners' food

Here "mourners' food" refers to what people would eat while they mourning because they were defiled and not acceptable to God. This means Yahweh will consider the people's sacrifices to be defiled and he will not accept them. (See: rc://en/ta/man/translate/figs-simile)

For their food will be for themselves only; it will not come into the house of Yahweh
