JERUSALEM — It’s gotten to the point where writing again about Sara Netanyahu, Prime Minister Benjamin Netanyahu’s embattled wife, can feel a bit like piling on.

She faces criminal charges of sneaking $100,000 in catered meals from expensive restaurants into the prime minister’s residence while covering up the fact that she had cooks on the government payroll. Two domestic workers have won damages in lawsuits accusing her of abusing them, and a third — a 24-year-old ultra-Orthodox cleaning woman who said she was treated like a “slave” — lasted barely a month in Mrs. Netanyahu’s employ last fall before fleeing and filing a complaint of her own.

Again and again, the Netanyahus’ defenders have sought to brand her accusers as malicious liars and political foes of her husband’s who are out to hurt him through her.

But on Sunday the Israeli public witnessed Mrs. Netanyahu’s stormy temper with its own ears: A recorded telephone conversation surfaced in which she berated a publicist over the way she had been described in a gossip column item about her fund-raising for a school her sons had attended.
