TLV is an interesting one as they often impose inbound slots on arriving aircraft.
To deal with your 'why haven't we pushed yet' query, it is better to take up airborne holding time at the gate from the departure then to have to burn fuel over the eastern Med whilst waiting for you arrival slot into TLV.
Ironically RYR use a +/- 15 minutes punctuality scheme whilst most other airlines use +/- 3 minutes.
Just food for thought.
