Similar envelopes with curses and white powder were received Sunday by two United Torah Judaism Knesset members.
The letters were taken by the Knesset officer and an investigation has been launched into the incident. The white substance had yet to be identified.
Opposition Chairwoman Tzipi Livni addressed the threat letters during a conference in the southern city of Yeruham. "I have heated arguments with haredi Knesset members, but I will be the first person to say that such actions must be condemned and denounced," she stated.
The letters sent to MKs Moshe Gafni and Uri Maklev contained, apart from the powder, some ugly curses. "We, the enlightened people of Israel, demand that you, people of darkness, stop living at our expense by studying without working, and get out of our lives," the letters said. "Stop sucking our blood, pack up your stuff and your shtreimels and go to Brooklyn.
"If you continue to squeeze out funds at our expense you will pay a hefty price, as we will fight you physically and not just through demonstration. You will feel our wrath on your selves and your synagogues. We will make your lives miserable and attack you in your cities and neighborhoods."
The letters, signed with a word play on "price tag policy", a name given by settlers to acts of revenge against Palestinians in the West Bank. Beneath was a picture of a skull wearing a traditional hat and side-locks.
