2 Chronicles 24:22  (King James Version)
Thus Joash the king remembered not the kindness which Jehoiada his father had done to him, but slew his son. And when he died, he said, The LORD look upon it, and require it.

Psalms 109:4 ; Luke 17:15-18 ; John 10:32

but slew his son
Proverbs 17:13

The Lord
These words were prophetic, and not imprecatory; and should be rendered as Houbigant proposes, in the future tense: "The Lord will look upon it, and avenge it." The event soon verified this prediction; for, before the year was expired, the Syrians came up against Jerusalem, and destroyed all the princes of the people, and Joash himself was slain in his bed by his own servants. Many circumstances served to aggravate this barbarous act. Zechariah was a high-priest and a prophet, upright and unblameable in the discharge of his high offices; this murder was perpetrated within the very precincts of the courts of the Lord; and this truly good man was by blood the nearest relative of Joash, and the son of the man who had save him from being murdered, and raised him to the throne!
