Hosea 9:4

They shall not offer wine-offerings to the Lord, in the drink-offerings, as representative of all unbloody sacrifices, neither shall (they) be pleasing unto Him their sacrifices, for the bloody offerings which they might consider bringing to Him would not be pleasing in His sight; (the food which they eat). shall be unto them as the bread of mourners, Cf Deuteronomy 26:14, because the food eaten upon such an occasion was regarded as unclean, since all objects in a house where there was a dead person were unclean, Numbers 19:14; all that eat thereof shall be polluted, being Levitically defiled by their meal, for their bread for their soul shall not come into the house of the Lord, that is, the food which they needed to support their life could not come into the house of God to be consecrated.
