John Calvin Commentary Isaiah 15:8

"For the cry is gone round about the borders of Moab; the wailing thereof unto Eglaim, and the wailing thereof unto Beer-elim." — Isaiah 15:8 (ASV)

The cry is gone round about the borders of Moab. כי, (ki,) for, is added for the sake of ornament. He means that every part of that country all around will be full of crying and howling, because that destruction reaches from one extremity to another. Besides the crying he twice mentions the howling, to denote the excess of grief, as people who are in despair surrender themselves entirely to lamentation.
