Albert Barnes Commentary 2 Kings 8:6

"And when the king asked the woman, she told him. So the king appointed unto her a certain officer, saying, Restore all that was hers, and all the fruits of the field since the day that she left the land, even until now." — 2 Kings 8:6 (ASV)

A certain officer - Literally, “a certain eunuch,” as noted in the margin. Eunuchs were at that time in common use at the Samaritan court (compare 2 Kings 9:32). They are ascribed to the court of David in 1 Chronicles 28:1, and we may conjecture that they were maintained by Solomon. Otherwise, we do not find them in the kingdom of Judah until the time of Hezekiah (Isaiah 56:3–4).
