Charles Ellicott Commentary Ezekiel 24:1

"Again, in the ninth year, in the tenth month, in the tenth [day] of the month, the word of Jehovah came unto me, saying," — Ezekiel 24:1 (ASV)

In the tenth day of the month. —Jehoiachin’s captivity (by which all these prophecies are dated) coincided with Zedekiah’s reign. The date here given is therefore the same as in Jeremiah 39:1; Jeremiah 52:4; 2 Kings 25:1, and was afterwards observed by the Jews as a fast (Zechariah 8:19). It was doubtless the day on which the investment of the city was completed.
