Albert Barnes Commentary 1 Kings 14:2

"And Jeroboam said to his wife, Arise, I pray thee, and disguise thyself, that thou be not known to be the wife of Jeroboam; and get thee to Shiloh: behold, there is Ahijah the prophet, who spake concerning me that I should be king over this people." — 1 Kings 14:2 (ASV)

Disguise yourself - Jeroboam fears that even Ahijah the Shilonite, who in a way made him king, will scarcely give his queen a favorable answer. The king’s conscience tells him that he has not performed the conditions on which he was promised “a sure house” (1 Kings 11:38).
