18 Joash king of Judah countered by gathering up all the sacred memorials - gifts dedicated for holy use by his ancestors, the kings of Judah, Jehoshaphat, Jehoram, and Ahaziah, along with the holy memorials he himself had received, plus all the gold that he could find in the temple and palace storerooms - and sent it to Hazael king of Aram. Appeased, Hazael went on his way and didn't bother Jerusalem.
Matthew Henry's Commentary on 2 Kings 12:18
Commentary on 2 Kings 12:17-21
(Read 2 Kings 12:17-21)
Let us review the character of Jehoash, and consider what we may learn from it. When we see what a sad conclusion there was to so promising a beginning, it ought to make us seek into our spiritual declinings. If we know any thing of Christ as the foundation of our faith and hope, let us desire to know nothing but Christ. May the work of the blessed Spirit on our souls be manifest; may we see, feel, and be earnest, in seeking after Jesus in all his fulness, suitableness, and grace, that our souls may be brought over from dead works to serve the living and true God.
