Albert Barnes Commentary 2 Chronicles 16:12

"And in the thirty and ninth year of his reign Asa was diseased in his feet; his disease was exceeding great: yet in his disease he sought not to Jehovah, but to the physicians." — 2 Chronicles 16:12 (ASV)

Yet in his disease he sought not... — Rather, “and also in his disease he sought not.” Not only in his war with Baasha, but also when attacked by illness, Asa placed undue reliance upon the aid of man.
