Charles Ellicott Commentary Jeremiah 48:20

"Moab is put to shame; for it is broken down: wail and cry; tell ye it by the Arnon, that Moab is laid waste." — Jeremiah 48:20 (ASV)

Make ye him drunken ... —The image is suggested by the wine-cup of Jehovah’s fury in Jeremiah 25:15, and was familiar in the symbolic language of the prophets (Isaiah 51:17; Job 21:20; Ezekiel 23:32; Revelation 14:10). The words that follow paint the image in its strongest colours. As people looked with scorn on the drunkard wallowing in his shame, so should they look on Moab, that had been so boastful in its pride, when it was brought low.
