Tafsiran 2 Raja-raja 12:3: Rashi & Tze'enah Ure'enah

All his days, as Yehoyoda the kohein instructed him. But after Yehoyoda died, the officers of Yehudah came to prostrate themselves before the king, and they deified him. They said to him, “One who enters the Holy of Holies for only a moment is in danger of dying, yet were hidden there for six years, so you are fit to be a deity.” Then the king listened to them.¹Shemos Rabboh 8:2.²Accordingly, the meaning of the verse is “all his days as Yehoyada the kohein instructed him,” i.e., as long as Yehoyada was alive.—Radak Or, “all his days” refers to Yehoyada’s days. After Yehoyada died, Yoash began to worship asheirohs and other idols. When Zecharyoh prophesied against him, Yoash had him killed, and the following year Arom attacked Yerusholayim.

“Jehoash did” [12:3]. Jehoash did what was good in the eyes of the Holy One, because Jehoiada taught him to do good. However, as soon Jehoiada died, Israel and the captains came to Jehoash and said to him. You were inside the Temple for six years, where the high priest goes only once a year, only on Yom Kippur. He was in great danger and was only there for one hour. You, Jehoash, were in the same place for six years and nothing happened to you. You must be a god. They bowed down to him and considered him a god. The king let it happen, to have them bow down to him as a god.²Rashi, II Kings, 12:3.
