Victor Kalisher was speaking after Israel was forced to deploy hundreds of soldiers across the country to support its police dealing with the incidents.
It also put up concrete barriers in some Arab neighbourhoods in East Jerusalem.
The latest attacks including a Palestinian man stabbing a 70-year-old Israeli woman, and another Palestinian man attempting to stab an Israeli policeman.
Both attackers were shot dead by police.
An Israeli has also been accused of committing a revenge stabbing on a Palestinian.
At least eight Israelis have been killed and 31 Palestinians since the beginning of October.
Of those 31, Israeli authorities identified 14 as terrorist attackers, with others being killed in clashes with police.
Palestinians have called the measures "collective punishment" that would make tensions worse.
While relations between Israelis and Palestinians are normally tense because of disputes over land, the latest attacks in October are a result of rumours that religious arrangements governing the holy site known as Temple Mount or Haram al-Sharif, which is revered by both Jews and Muslims, were to be changed in favour of Jews.
Victor Kalisher told Premier's News Hour: "I think that it is a spiritual war, it is really evil spirits taking over people, and it is the fruit of many years of hatred and so on that grew up. It is like a volcano, it's there and there and then it erupts.
"If the leaders have the wisdom and the mercy from God to overcome the feelings right now and tell people to calm down this would really help.
"I think we need to pray that the Spirit of the true God will overcome the evil spirits that are trying to get over the hearts of people, this could really help.
"And I think we really need to pray... that God would really watch over our hearts and protect us to be the salt and light because it is a really dangerous situation and we need to be a testimony of love and peace."
