Printing line "x" in a file

I have a script where I need to get the text from line number "$line" in file "$filename" then save it to a var ($text) and then print it. For example, in the file lamb.txt (just an example file): "Mary was a little lamb, whose fleece was as white as snow." I need to get line number 3 ("fleece") and print it ("print $text"). How would I go about this? Andrew Conner (All apologies if this messes up and does a multi-post)
