Albert Barnes Commentary Ezekiel 20:1

"And it came to pass in the seventh year, in the fifth [month], the tenth [day] of the month, that certain of the elders of Israel came to inquire of Jehovah, and sat before me." — Ezekiel 20:1 (ASV)

The elders of Israel - These were as in Ezekiel 14:1, some of Ezekiel’s fellow-exiles, designated in general terms by the name of Israel, though more properly belonging to the kingdom of Judah.
