Charles Ellicott Commentary 1 Chronicles 23:22

"And Eleazar died, and had no sons, but daughters only: and their brethren the sons of Kish took them [to wife]." — 1 Chronicles 23:22 (ASV)

And Eleazar died, and had no sons. —Thus his house merged into that of the sons of Kish, who married his daughters according to the Law (Numbers 36:6–9). The sons of Mahli, then, were represented in David’s day by the house of Kish. (See 1 Chronicles 24:29.)
