Observation: In this section of 2 Samuel, the author reports on David's military might, immediately followed by David's sin of taking a census of his military might. However, this first section addresses David's "mighty men". And who are they? Well ...
Let's start with "the three". These are the mightiest of the mighty men, but they are not the mighty men. They are Josheb-Basshebeth, Eleazar, and Shammah, and they were commanded by Abishai. So ... there were four of "the three". Then we have "the thirty", who are commanded Benaiah who is not one of the thirty nor one of the three, followed by the list of the thirty in which thirty-seven are listed.
So in summary ... there are "the three" which are really four, and "the thirty" which are really thirty-seven but really really thirty-eight, so obviously ... 3+30=42.
Application: I know there are very serious and important elements of the bible that are difficult to understand and worthy of deep thought (David's acts that follow this section - taking a census of the fighting men - is one such example). And then there is something like this that is just kind of fascinating, and maybe even a good case study about why understanding the ancient writing of the bible is so difficult.
Obviously, and for reasons I cannot fathom, there is some sort of historical or cultural context around why there is a special designation for three great warriors, and another special designation around 30 exceptional warriors, however the actual counts don't match, and the commanders (who the text even says are equal or greater than the others) aren't included. If feels like, perhaps, the numbers carry some cultural importance, even if the actual count doesn't equal the numbers. Or maybe David wanted to honor certain individuals and he had a limited number of titles to hand out, so he created a designation then couldn't bring himself to be limited by the arbitrary cut-off point. Or maybe, just like we see throughout the bible, the REAL number here is 40, and all of this actually represents two commanders and their 40 great warriors, and it's all just a code for the idea that "David had a lot of great warriors".
My personal takeaway is ... this sort of stuff is just fun to think about. I love the idea that it is almost impossible to fully understand scripture, and that a simple matter of a list of names along with a numbering system that doesn't match is just one way of realizing that language, custom, culture, and God's own divine methods all play a part in understanding scripture and how it reveals the Lord's heart and plan.
Prayer: Lord, you are for sure the God of mysteries, and I love that about you. Thank you for your blessings in our lives, and even for those things in life that we cannot possibly understand or even know. It all reveals your greatness. Amen.
