1 Chronicles 3:21,22

The sons of Shechaniah All these, both parents and their sons blended together, are mentioned as the sons of Hananiah, and branches of the royal stock. Six Including the father. But the Hebrew word, shisha, which is rendered six, may be the proper name of one of the sons of Shemaiah. As the family of David was the most considerable of any of the tribe of Judah, the genealogy of his descendants was preserved with great care and exactness; and is here recorded in part, to assist us in tracing the descent of our Lord Jesus Christ from him, that we might have that proof, among others, of his being the true Messiah.
