Reading David in the I Chronicles Genealogies

I have just come to that place in my Bible reading that at points can seem to be laborious, if not engaged with the right perspective. The section I am referring to is I Chronicles 1--11, you know, pretty much pure genealogy. So it requires extra concentration to stay focused while reading through here. A couple things that help provide focus is to ask "why" God felt it so important to include this genealogical section in the Scriptures in the first place? I think the primary answer to that is to realize, as with everything else in Scripture (cf. Jn. 5:39), that the genealogy provides the Messianic/Davidic line; or, Jesus' line. Note:

King David

5. The sons of Perez were Hezron and Hamul. 6. The sons of Zerah were Zimri, Ethan, Heman, Calcol, and Dara--five of them in all. 7. The son of Carmi was Achar, the troubler of Israel, who transgressed in the accursed thing. 8. The son of Ethan was Azariah. 9. Also the sons of Hezron who were born to him were Jerahmeel, Ram, and Chelubai. 10. Ram begot Amminidab, and Amminidab begot Nahshon, leader of the children of Judah; 11. Nahashon begot Salma, and Salma begot Boaz; 12. Boaz begot Obed, and Obed begot Jesse; 13. Jesse begot Eliab his firstborn, Abinidab the second, Shimea the third, 14. Nethanel the fourth, Raddai the fifth. 15. Ozem the sixth, and David the seventh. ~I Chronicles 2:5-15

An interesting note, that David is the "seventh," is that 7 is the number of perfection or completion. Let's also cross reference this genealogy with another one:

18. Now this is the genealogy of Perez: Perez begot Hezron; 19. Hezron begot Ram, and Ram begot Amminadab; 20. Amminadab begot Nahshon, and Nahashon begot Salmon; 21. Salmon begot Boaz, and Boaz begot Obed; Obed begot Jesse, and Jesse begot David. ~Ruth 4:18-21 

And then one more cross reference:

3. Judah begot Perez and Zerah by Tamar, Perez begot Hezron, and Hezron begot Ram. 4. Ram begot Amminadab, Amminadab begot Nahashon, and Nahashon begot Salmon. 5. Salmon begot Boaz by Rahab, Boaz begot Obed by Ruth, Obed begot Jesse, 6. and Jesse begot David the king. . . . ~Matthew 1:3-6a

Who said genealogies couldn't be fun to read? For me, this helps as I approach I Chronicles 1--11 in particular; knowing that in fact the primary line being established is that of Jesus' Messianic Davidic line that is the line that brings salvation to the nations, thus making Abraham the Father of many nations. This is good stuff. One other important thing about these genealogies, is to bear in mind that what God has established in salvation history, over centuries of time, through multitudes and multitudes of faceless normal people; is his anointed line, and this line comes through everyday people who end up getting listed in a genealogy in the Bible. That is, pastorally, encouraging to me. This demonstrates how significant each of our lives are, because they are tied to the line of David in Christ.

I hope this brief little reflection on I Chronicles 1--11 helps provide you with some more perspective the next time you are faced with reading through this section of Scripture.
