“Heaven (shmayo), and all that we call ‘heaven’ (shmayo), is not of our speech, of us Arameans, that is, the language of Mesopotamians. And it is not from our language and speech, but is borrowed and taken for us from the language of the Hebrews.”
Saint Jacob of Edessa identifies himself as an Aramean and sees Arameans being Mesopotamians. He claimed that the word “heaven” (shmayo) is a loanword.
