Albert Barnes Commentary Ezra 10:2

"And Shecaniah the son of Jehiel, one of the sons of Elam, answered and said unto Ezra, We have trespassed against our God, and have married foreign women of the peoples of the land: yet now there is hope for Israel concerning this thing." — Ezra 10:2 (ASV)

Jehiel was one of those who had taken an idolatrous wife (Ezra 10:26); and Shechaniah had therefore had the evil brought home to him.
