Jerome : (Verse 4.) Esbon and Eleale will cry out. These are the names of cities in the province of Moab, of which Esbon was once the city of the Amorite king. Concerning this city, Jeremiah also said, 'Fire has come out of Esbon, and a flame from the midst of Seon.' The name Esbon means 'thought' and therefore, Jeremiah, alluding to the name, says against Esbon, 'they have devised evil.' (Jeremiah XLV.) The voice of them was heard even to Jaza. The city of Jaza (also known as Jasa) lies close to the Dead Sea, where the border of the Moabite province is. This indicates that the wailing of the province will resound to the very ends of the land. Hence, Jeremiah also says: From the outcry of Heshbon, even to Eleale and Jaza, they have raised their voice (Jeremiah 48:34). Therefore the Moabites will wail, every one will wail for himself; for the raisin cakes of Kir-hareseth you shall mourn, utterly stricken. But if, as Aquila wanted, they are understood to be exerting their shoulders, that suggests to us the feeling that everyone has bared their chests to mourn. — Commentary on Isaiah Jerome : (Verse 4) Then they shall understand all their vain thoughts, which are interpreted as Esbon, and the futile ascent of pride, which sounds like Eleale, so that the voice of their deeds may be heard, and the commandment they thought was from God, condemning themselves by their own confession. Therefore, the bars, that is, those who were strong in Moab and understood their error, shall howl, and they who had hopes will begin to have regrets when their soul howls to itself. — Commentary on Isaiah
