Albert Barnes 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)

The prophecies in this chapter were delivered two years and five months after those of the previous section (Ezekiel 20:1). The day mentioned here was the very day on which Nebuchadnezzar completed his arrangements for the siege, and closed in the city (marginal references). After the captivity this day was regularly observed as a fast day (Zechariah 8:19).
