1 Chronicles 4:27
And Shimei had sixteen sons and six daughters; but his brethren had not many children, neither did all their family multiply, like to the children of Judah. And Shimei had sixteen sons and six daughters; but his brethren had not many children, neither did all their family multiply, like to the children of Judah.
The verse stands in the genealogy of Judah, within the first nine chapters of Chronicles which consist almost wholly of genealogies. Chronicles takes knowledge of Samuel and Kings for granted, supplying what they left out with many new and important facts, and it gives more detail about Judah than Kings does. Such family records were kept in great numbers because after the exile they were needed to assign the land to its hereditary owners and to restore the temple service to those whose hereditary duty it was.
The family lines of Judah were carefully preserved unbroken until Christ's first advent because Christ came through that tribe. The counting of Shimei's sixteen sons and six daughters and the smaller increase of his brethren is among the notable details of that genealogy. Its place in the record shows that God keeps a faithful record of each soul.
