Found this, looks like those planes are going to be converted to freighters and part planes:

That is changing. The airline recently purchased four 767-300 passenger aircraft, two of which it is having converted to freighter configuration by Bedek Aviation Group, the MRO arm of Israel Aerospace Industries, and two that will be used for parts only. The first of the freighter converted 767s is scheduled to begin operations in May 2016. The second 767 was scheduled to be ferried to the Bedek facility in Tel Aviv for conversion Feb. 1, and should enter service around mid-year. And more may be on the way. Connie Kalitta recently said the carrier was planning to acquire as many as five or six more 767s “in the near future.”
