Helpful to ask for this so you won't have to leave security, collect your bag, recheck it, then clear security again. It's not as big an issue on the way back if you can only check your bag to EWR, since regardless of how your bag is tagged, you'll have to collect it at Customs in EWR and recheck it.

Also remember that at EWR, the TLV flight has a secondary screening at the gate, so get to the gate earlier than you normally would.
