Ezekiel 8
Vision of Idolatry in the Temple
1And it came to pass in the sixth year, in the sixth
month, in the fifth
day of the month,
as I sat in mine house, and the elders of Judah sat before me, that the hand of the Lord GOD fell there upon me.
When God's last sacrifice takes place in the Eve, the date has just changed to the 6th day in the 6th month, in the 6th year, and that is the calculation that only a Jewish minded person would realize.
