Likely “grandmother”

“mother’s.” The Hebrew text is “mother,” but “father” and “mother” were also used for grandparents and ancestors. Normally verses such as this tell us the name of the actual mother of the king (cp. 1 Kings 15:2; 2 Kings 8:26; 12:1; 14:2; 15:2, 33; 18:2; 22:1, etc.). The fact that this verse gives us the name of the grandmother shows the tremendous influence she held in the kingdom. But she was an idol worshiper and Asa removed her from her royal position (1 Kings 15:13).
