Ezekiel 1:1, 3

Now it came about in the thirtieth year, on the fifth day of the fourth month, while I was by the river Chebar among the exiles, the heavens were opened and I saw visions of God.

the word of the LORD came expressly to Ezekiel the priest, son of Buzi, in the land of the Chaldeans by the river Chebar; and there the hand of the LORD came upon him.)
