The former jailhouse rabbi who lost his job for granting favors to Jewish inmates pleaded not guilty in Manhattan federal court yesterday to charges he scammed more than $220,000 in federal-housing benefits.

Rabbi Leib Glanz — who quit as a correction chaplain after The Post exposed a bar mitzvah bash he arranged in the Tombs — is accused with his brother of running a 15-year fraud on the Section 8 rent-subsidy program for the poor.

Feds say Glanz swindled up to $1,675 a month in taxpayer funds by illegally occupying a Brooklyn duplex that had been approved for his brother, Menashe, who lived in a home nearby.

He allegedly pulled off the scam by signing a housing contract on behalf of the building’s owner, the United Talmudical Academy, which he once ran.

Leib’s lawyer, Alan Vinegrad, declined comment.
