John Gill Bible Commentary

Thou shouldest not have entered into the gate of my people in the day of their calamity,.... Or gates, as the Targum; the gates of any of their cities, and particularly those of Jerusalem; into which the Edomites entered along with the Chaldeans, exulting over the Jews, and insulting them, and joining with the enemy in distressing and plundering them: yea, thou shouldest not have looked on their affliction in the day of their calamity: which is repeated, as being exceeding cruel and inhuman, and what was highly resented by the Lord; that, instead of looking upon the affliction of his people and their brethren with an eye of pity and compassion, they looked upon it with the utmost pleasure and delight: nor laid hands on their substance in the day of their calamity; or "on their forces" (x); they laid violent hands on their armed men, and either killed or took them captive: and they laid hands on their goods, their wealth and riches, and made a spoil of them. The phrase, "in the day of their calamity", is three times used in this verse, to show the greatness of it; and as an aggravation of the sin of the Edomites, in behaving and doing as they did at such a time. (x) "is exercitum ejus", Drusius; "in copius eorum", Castalio; "in copiam ejus", Cocceius.
