“25th year of our captivity.” Ezekiel 38 and 39 are one vision, and Ezekiel 40:1 starts another. All of the dates like this one in Ezekiel—“In the 25th year of our captivity, in the beginning of the year, on the tenth day of the month, in the 14th year after the city was struck down”—are reckoned from the captivity of Jerusalem when King Jehoiachin was taken captive in 597 BC (2 Kings 24:8-17). This date in Ezekiel 40:1 would be 573 BC. When Nebuchadnezzar conquered Judah during the reign of Jehoiakim (2 Kings 24:1; 2 Chron. 36:5-8) he took “some” of the articles of Yahweh’s Temple to Babylon (2 Chron. 36:7; Dan. 1:2). But when he conquered Judah again after Jehoiakim’s rebellion and installed Jehoiachin, he took “all” Yahweh’s treasures to Babylon (2 Kings 24:13; 2 Chron. 36:10).
“captivity.” The Hebrew can also be translated “exile.” This was the captivity of Judah, when the people were taken captive to Babylon.
“after the city was struck down.” That is, after Nebuchadnezzar’s army destroyed Jerusalem and burned it.
“and he brought me there.” That is, Ezekiel was brought to the land of Israel in his vision. He could see Jerusalem (Ezek. 40:2), but he was brought to the Temple, which was north of the city of Jerusalem.
