Narrative:
Level flight at 6000' inbound to colts neck VOR departing ewr on newark III departure. ATC gives heads up call of traffic 12 to 2 O'clock descending into lga. We spot large transport about 2 O'clock slightly high 3-4 mi. ATC issues us an immediate descent to 5000' and advises that 2 O'clock has descended below 7000'. We began our descent and observed 2 O'clock traffic to climb. We then were cleared back to 6000'. At no time did we perceive collision threat. Traffic passed 2-3 mi.
