2 CHR.33 [3] For he built again the high places which Hezekiah his father had broken down, and he reared up altars for Baalim, and made groves, and worshipped all the host of heaven, and served them.[4] Also he built altars in the house of the LORD, whereof the LORD had said, In Jerusalem shall my name be for ever.[5] And he built altars for all the host of heaven in the two courts of the house of the LORD.[6] And he caused his children to pass through the fire in the valley of the son of Hinnom: ALSO HE OBSERVED TIMES, and used enchantments, and used witchcraft, and dealt with a familiar spirit, and with wizards: he wrought much evil in the sight of the LORD, to provoke him to anger
Enchantments, witchcraft, familiar spirits, and wizards. Its speaking of the occult. Not following sabbath days.
LEV.19 [26] Ye shall not eat any thing with the blood: neither shall ye use enchantment, NOR OBSERVE TIMES.[27] Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard.[28] Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD.[29] Do not prostitute thy daughter, to cause her to be a harlot; lest the land fall to whoredom, and the land become full of wickedness.[30] YE SHALL KEEP MY SABBATHS, and reverence my sanctuary: I am the LORD.
I guess this scripture says it all. You shall not observe times BUT you will keep my sabbaths.
