Benitez has been eager to set the record straight on his time at Anfield, pointing the finger at former Reds managing director Christian Purslow last month when he memorably said that "white liquid in a bottle has to be milk".
Benitez has now turned on Hodgson, who claimed over the weekend that Dalglish had not been allowed to set foot in the club's training ground during the Spaniard's reign.
"I think that Mr Hodgson, he doesn't understand," Benitez said. "Every single press conference is even worse than the last one.
"He's talking about things that he doesn't know, and some people cannot see a priest on a mountain of sugar.
"Maybe he hasn't been in Liverpool too long. We gave the fans their pride - again. We fought for the fans, we fought for the club and we fought for our players, so maybe he cannot understand this."
He added: "I brought back Kenny Dalglish to do a role in the club and Christian Purslow gave him another role.
"He (Hodgson) doesn't know but I will explain it to him. So, instead of talking about the flips or the flops, he has to concentrate on his players, try to do his best. He has a good job to do."
Hodgson has also suggested that the squad he inherited is not equipped to compete at the highest level, but Benitez believes he is diverting attention from performances.
"They've signed nine players," he said. "With £10 million net spending, I left that squad with £300 million value, 13 internationals.
"So, instead of talking about flips and flops, he has to concentrate on his job, try to do his best and not talk about the level of his players or the new players.
"Concentrate, try to do your best, because it will be the best for the club and it will be the best for the fans."
