1 Chronicles 9 (Ezra 2.43, 79, Ezra 8.20, and Nehemiah 7.73)
This opening verse should be a warning to all who read. When we allow our hearts to turn from the Word, will, and way of God we are unfaithful to Him. Our unfaithfulness may not lead to physical captivity, but our hearts, minds, and wallets can become captive to the world system we are told to stay away from (1 John).
As can be seen by the passages listed above, this chapter details those who returned from the Babylonian Exile. The first to return (9.2) are the laymen, priests, Levites, and temple servants. This last group of people is called the Nethinim in the Hebrew text. These people were a group of temple servants (see references above) who helped the Levites with the menial chores in the Temple. The moniker Nethinim means “those who are given.” In the cross-references above, read in context, the Nethinim have Gentile names. This has led many to hold that these were non-Israelites. However, having a non-Israelite serving in the Temple has caused some to disregard that view. The names given could have been given to the foreign-born Israelite merely because they were in a foreign land (think of the four in the book of Daniel whose names were changed).
When this chapter is completed, the legitimacy of the Israelite nation from Creation to the moment of return from Exile is given. This is the nation that belongs in the Promised Land. Be thankful that your genealogy only needs to include Jesus as your Savior for you to inherit and claim legitimacy as one who is possessed by the King of the Promised Land.
The books of the Bible are divided into chapters by men. This is one case where I would have chosen a different point of separation. First Chronicles 9.35 could have been 1 Chronicles 10.1. This is because this portion of the book deals with the material in chapter ten that of King Saul. The closing of 1 Chronicles 9 presents the linage of King Saul (35-44). The ending of this chapter sets the stage for chapters ten and following. However, I do see that it is attached to chapter nine because it is a genealogy.
