I'm not too sure if this painting is legit or AI generated, but an inversed masonic lambskin apron could have multiple meanings here.

It is symbolic of the purity and innocence men are expected to pursue in life as a Freemason. Albert Mackey, the famous Masonic historian who wrote of the apron in the Encyclopedia of Freemasonry remarked that it is the first symbol explained to a new Brother and the first evidence of his commitment to the Fraternity.

Jesus is the lamb of God and their lambskin aprons represent the opposite of God (lucifer), they pretend to be faithful, pure and innocent Christians in public, but in reality they are just the foot soldiers and servants of the devil.

As above, so below. This painting depicts a black vs white (magick) masonic occult ritual, and in my opinion it's nothing more than a mockery and abomination to God and Jesus Christ.
