Albert Barnes Commentary 1 Chronicles 27:4

"And over the course of the second month was Dodai the Ahohite, and his course; and Mikloth the ruler: and in his course were twenty and four thousand." — 1 Chronicles 27:4 (ASV)

The words “Eleazar, son of,” have probably been omitted before the name Dodai (or Dodo). According to Jewish tradition, Eleazar (1 Chronicles 11:12) was David’s cousin, as his father, Dodai, was Jesse’s brother. Mikloth was probably second in command to Eleazar.
