grep help, how do i make this shorter?

[UniXman1234]

Hi everyone, im trying to make the following command line shorter by
introducing a script that join up all the grep commands

 ./new1a < numbers.txt | grep -i -v '^a ' | grep -i -v '^the ' | grep -i -v
'^or ' | sort -f

How would I go about merging all the greps into a scripe and putting all the
words that should be excluded into a data file

so would it be something like this

---exclude---

#!/bin/sh
# exclude.sh

grep -i -v ^datafile.txt
----end--------------

---datafile.txt---
a
the
or
---end.txt---


so i would be able to execute it like

./new < numbers.txt | exclude | sort -f

Thank you, i tried doing every possible way i could think of but it doesnt
seem to work. Im a newb just started script programming 2 weeks ago
