You pick up the phone and negotiate a hostage exchange.
You say, meet us at this spot tomorrow with 10 of the oldest and youngest hostages you’ve got and we’ll do the same. If it goes well, we’ll talk about doing another exchange the next day.
That’s what Hamas wants. That’s what they’ve usually taken and returned hostages for. Hamas released two hostages so far in the weeks this has been going on. How come someone negotiated for 2 and then stopped there?
