Joel 3:19

(19) Egypt shall be a desolation.—Egypt and Edom always excited feelings of abhorrence in the hearts of the Jews. The memory of the exile in Egypt was always fresh and keen; no retrospect of their past history could leave it out of account. And the national detestation of the false and cruel-hearted Idumæan kinsmen is recalled by Obadiah in his prophecy and touching record; as also in Psalms 137:0, as rendered in the Prayer Book, “Remember the children of Edom, O Lord, in the day of Jerusalem, how they said, Down with it, down with it, even to the ground.”
