Weird. There’s one, lonely, Aramaic verse in Jeremiah. It’s Jer 10:11, “Thus shall you say to them: ‘The gods who did not make the heavens and the earth shall perish from the earth and from the heavens.'”
Carey Moore in his book Esther, Daniel and Jeremiah contends that this verse is the basis for the Letter of Jeremiah, which mocks idol worship (Bar 6). It repeats the fact that idols are not gods over and over. But, how weird is that there is just one, only one, Aramaic verse in the whole Hebrew book of Jeremiah!
