grep

There are often times I'll grep -l whatev file to find what I'm looking for. Say the output is

1234: whatev 1
5555: whatev 2
6643: whatev 3

If I want to then just extract the lines between 1234 and 5555, is there a tool to do that? For static files I have a script that does wc -l of the file and then does the math to split it out with tail & head but that doesn't work out so well with log files that are constantly being written to.
