1 Kings 15:13
And also Maachah his mother, even her he removed from being queen, because she had made an idol in a grove; and Asa destroyed her idol, and burnt it by the brook Kidron. And also Maachah his mother, even her he removed from being queen, because she had made an idol in a grove; and Asa destroyed her idol, and burnt it by the brook Kidron.
The verse belongs to the history of the separate kingdoms of Judah and Israel after the division, a history spanning about eighty years and recording the reigns of several kings. It was a time of war and strife between the two divisions. Within that history it belongs to the record of Asa's reign in Judah after Abijah, his better reign over Judah coming after the brief reign of the wicked Abijam, also called Abijah, under whose sway Judah prospered.
The account highlights idolatry and its punishment. It gives object lessons about the fruits of righteousness, backsliding, and sin.
