And Heshbon shall cry, and Elealeh: their voice shall be heard even unto Jahaz: therefore the armed soldiers of Moab shall cry out; his life shall be grievous unto him.
Heshbon - an Amorite city, 20 miles east of Jordan; taken by Moab, after the carrying away of Israel, (cf. Jer
48.)
Elealeh - near Heshbon, in Reuben.
Jahaz - east of Jordan, in Reuben. Near it Moses defeated Sihon.
Therefore - because of the sudden overthrow of their cities.
The armed soldiers of Moab shall cry out - even the armed men, instead of fighting in defense of their land, shall join in the general cry.
His life shall be grievous unto him - rather, 'his soul is grieved' (1 Samuel 1:8) (Maurer). Compare with the English version, Revelation 9:6.
