According to flightradar24, LH694 was FRA 21:35 - TLV 02:40 until 10 July. Then the schedule changed to FRA 22:05 - ATH 01:15 / 04:00 - TLV 06:00 for a few days until all flights to TLV were cancelled on 22 July.
It could be to avoid arriving at night as daumueller suggested. It could also be to change crews in ATH, so the same crew could operate ATH-TLV-FRA without the need to overnight in TLV.
