The day of the Lord; a day of (or, to) Jehovah cometh. The Greek and Latin Versions have the plural, "days of the Lord come." It is a time when he will specially manifest his glory and power, and be recognized as allowing the trial of his people for wise purposes.
It is impossible to fix on any historical fulfilment of this prophecy. The details suit neither Maccabean nor Roman times; the attempt to define exactly the period and matter of its accomplishment has proved a failure, and has led to a mingling of events of very different dates, and to a conglomeration of senses literal, metaphorical, and anagogical, which creates confusion while assuming to explain difficulties.
The literal interpretation must be resigned, and the whole prophecy must be taken to adumbrate the kingdom of God in its trial, development, and triumph. Thy spoil shall be divided. Jerusalem is addressed; and the prophet intimates that the enemy shall get possession of the capital, plunder it, and divide its spoil among themselves in its very midst with the greatest security, the inhabitants being wholly at the conquerors' mercy.
