President Biden wasn't supposed to shake hands with any foreign leader during his first Middle East trip .
It's a precaution aides said was meant to protect him from Covid - 19 -- but one that would conveniently help avoid a handshake with Saudi Crown Prince Mohammed bin Salman on the second leg of his tour .
But in this video , you can see him fist - bumping the Israel premier and several other officials after stepping off Air Force One in Tel Aviv .
He later had an extended handshake with Israel's former Prime Minister Benjamin Netanyahu .
