C. F. Keil and Franz Delitzsch on 1 Chronicles 4:34-37

1Ch 4:34-37 Emigrations of Simeonite families into other districts. - 1Ch 4:34-41 record an expedition of the Simeonites, in the time of Hezekiah, undertaken for purposes of conquest. In 1Ch 4:34-36, thirteen princes of the tribe of Simeon are enumerated who undertook this expedition. The families of some of them are traced through several generations, but in no case are they traced down so far as to show their connection with the families named in 1Ch 4:24-26.
