John Gill Commentary 1 Kings 22:46

"And the remnant of the sodomites, that remained in the days of his father Asa, he put away out of the land." — 1 Kings 22:46 (ASV)

And the remnant of the Sodomites, which remained in the days
of his father Asa, he took out of the land .
] His father Asa removed many of these filthy creatures, but not all; as many, no doubt, as came within his knowledge, but some remained, whom his son removed, being of the same disposition with his father, see (1 Kings 15:12) .
