Ezekiel 4:9 commands making the bread from mixed grains — the very bread that is then baked on dung and declared unclean in v13.

Daniel 1:8 shows Daniel actively resisting unclean food in exile — contrasting with the prophecy here that Israelites will inevitably eat defiled bread.

Hosea 9:3 similarly prophesies eating unclean food in exile — directly echoing the same judgment of defilement among the nations.

Hosea 9:4 adds that exiled Israelites' bread will be defiled like mourners' bread — reinforcing the uncleanness prophesied here.

Amos 7:17 also prophesies exile and defilement among Gentiles, reinforcing God's warning that Israel will eat defiled bread in captivity.
