And Jehu said, proclaim a solemn assembly for Baal
Such as with the Jews was an holy convocation, when they were forbidden and restrained from doing any work on that day; and such a day Jehu would have appointed and proclaimed for Baal, that the people might be at leisure to attend:

and they proclaimed it;

Melachim Bais 10:20 In-Context

18 And Yehu gathered kol HaAm together, and said unto them, Ach’av served Ba’al a little; but Yehu shall serve him much.

19 Now therefore summon unto me all the nevi’im of Ba’al, all his avadim, and all his kohanim; let none be wanting; for I have a zevach gadol to do to Ba’al; whosoever shall be wanting, he shall not live. But Yehu did it be’akbah (in cunning, in deception), to the intent that he might destroy the ovdei HaBa’al (worshippers of Ba’al).

20 Yehu said, Proclaim an atzeret (a solemn assembly) for Ba’al. They proclaimed it.

22 And he said unto him that was over the meltachah (wardrobe), Bring forth levush (robe) for all the ovdei HaBa’al. And he brought them forth the malbush (vestments, religious robes).
