How do I create a bounded range type in the SQL Server?
Besides SQLCLR, you could also store both values in either XML or JSON (if you are using SQL Server 2016 or newer) and retrieve them as discrete values. Similarly you could simply convert them to VARCHAR and place them, separated by a comma, in a single column (I don't recommend this at all, but it is functionally similar to the other approaches I just mentioned). The SQLCLR approach makes it easy to get the discrete values back out, and in their native datatypes, but you could just as easily write a few helper UDFs to do the same with those values shoved into XML or JSON.

In all of these cases, while you could accomplish the goal of storing two values in a single column, I don't see what you gain by doing this given that each approach has some amount of overhead yet the usage doesn't seem to justify it. The main reason for creating your own type isn't to merely associated related data points, but to have the ability to act upon them. The internal CLR types not only store the discrete data points, but also offer quite a few methods to do interesting things with those data points. I am not sure what you can do operationally with just beginning and ending numbers that don't have commonly used algorithms for making use of them. It seems that you will be doing more work to get the values back out (and most likely decrease performance while doing so) than you will be gaining by putting them in such a structure.

Unless you can clearly see a guaranteed benefit from doing this, I suggest you keep them as discrete data points. And if my memory serves me correctly, you should be able to get away with using TINYINT, assuming no verse # goes above 255 (and they certainly wouldn't be negative or NULL). Looking here ( New Testament Statistics ) and here ( Old Testament Statistics - New American Bible ) it seems that the highest verse number is 80 for the New Testament (Luke chapter 1), and 176 for the Hebrew Bible &mdash; "Old Testament" in Christian terminology &mdash; (Pslam 119).
