Remember, O Lord, the children of Edom in the day of Jerusalem; rather, remember, O Lord, to the children of Edom the day of Jerusalem. "The day of Jerusalem" is the day of her fall, when Edom took part with her enemies, and rejoiced at her destruction (see Lamentations 4:21, Lamentations 4:22; Ezekiel 25:12; Ezekiel 35:5; Obadiah 1:10-14).
The psalmist prays God to "remember" this to Edom, and requite it upon her (comp. Psalms 132:1, where the same expression is used in a good sense). Who said, Rase it, rase it, even to the foundation thereof; i.
e. "destroy the city utterly—leave not one stone upon another." The enmity between Edom and Israel was of the intensest character (see 1 Kings 11:15, 1 Kings 11:16; 1 Chronicles 18:12; Jeremiah 49:7-22; Amos 1:11, Amos 1:12; Malachi 1:3-5).
