Ezekiel 1:1

Now it came to pass in the thirtieth year, in the fourth month, in the fifth day of the month, as I was among the captives by the river of Chebar, that the heavens were opened, and I saw visions of God.

Thirtieth year — From the finding the book of the law in the eighteenth year of Josiah, from which date to the fifth year of the captivity are thirty years.

Fifth day — Probably it was the sabbath-day, when the Jews were at leisure to hear the prophet.

River — Perhaps retiring thither to lament their own sins, and Jerusalem's desolation.

Chebar — A river now called Giulap, arising out of the mountain Masius, and falling into Euphrates, somewhat below a city called by the same name.
