Yet served

However every nation continued to make gods of its own, and put them in the shrines on the high places which the Samaritans had made, every nation in the cities where they dwelt. The men of Babylon made Succoth Benoth, the men of Cuth made Nergal, the men of Hamath made Ashima, and the Avites made Nibhaz and Tartak; and the Sepharvites burned their children in fire to Adrammelech and Anammelech, the gods of Sepharvaim.  So they feared the Lord, and from every class they appointed for themselves priests of the high places, who sacrificed for them in the shrines of the high places. They feared the Lord, yet served their own gods—according to the rituals of the nations from among whom they were carried away. 2 Kings 17:29-33

They “feared” the Lord, yet served their own gods!
