A Long Island cantor is singing the blues after being sued by the Trump Taj Mahal Casino in Atlantic City over a $26,000 gambling debt.

Eitan Binet, 39, of Bellmore, a cantor at the town’s Temple Beth-El, got $35,000 in credit from the New Jersey casino on Jan. 8, 2009, a source familiar with the recent lawsuit filed in Nassau Supreme Court told The Post.

After much of it was lost at the tables, Binet, a restaurant entrepreneur and father of three, wrote the casino a check for the $26,000 — but it bounced, the source said.

He made a $10,000 payment in September, the source said, but with interest, he still owes the casino $16,638.63.

Binet told The Post he was never notified that a lawsuit was filed against him, and said he feels hounded. He also said he fears losing his job.

“I wanted to settle with them and I never heard from them,” said Binet. “I got a marker. I’m willing to pay them.”

Neither the casino nor the law firm that filed the suit would comment on the legal action.
