Jeremiah 48:1-5 already details Moab's destruction and shame—this verse continues the same proclamation of ruin.

Jeremiah 48:8 earlier predicts the destroyer's arrival on all Moab's cities, directly feeding into the wailing commanded in 48:20.

Numbers 21:14 cites an ancient poem mentioning the Arnon, the same river where Jeremiah calls Moab to wail over its shame.

Isaiah 15:1-5 is a parallel oracle wailing over Moab's devastation, matching the cry and shame declared here.

Isaiah 16:2 describes Moab's daughters fleeing at the fords of the Arnon, directly paralleling Jeremiah's image of Moab's shame at the same river.

Isaiah 15:8 says the cry over Moab spreads to its borders—echoing the command here to broadcast the news in Arnon.

Judges 11:18 identifies the Arnon as Moab's border, providing contextual background for Jeremiah's proclamation of shame at that very boundary.
