Who is supposed to be worshipped here ? Allah and Masih aka Jesus

their priests and monks

Quran 9:31
They have taken their scholars and monks as lords besides Allah , and [also] the Messiah, the son of Mary. And they were not commanded except to worship one God; there is no deity except Him. Exalted is He above whatever they associate with Him.
see the translators inserted also in bracket when it wasn't originally there to islamicze it and avoid the contradiction elsewhere.
