Joash was grateful to Jehoiada, the priest who guided him. Joash stayed loyal to the Lord while Jehoiada lived. However, after Jehoiada died, ungodly leaders persuaded Joash to abandon the Lord and adopt Canaanite customs (see 2 Chronicles 24:17–22).
Joash's failure to destroy the pagan shrines led to spiritual compromise. Allowing these shrines in Judah had previously angered God (1 Kings 14:23–26) and would do so again during Joash's time (2 Chronicles 24:23–24).
