"There's a saying when the devil ignores you, then you know you're doing something wrong...Conversely, when the devil comes at you, maybe it's because he's trying to do something right. And for whatever reason the devil got a hold of him that night," Washington told Jakes.
Declining to reveal what else the men discussed, Washington told Jakes that they prayed together.
"Who are we to condemn? I don't know all the ins and outs of this situation, but I know the only solution was prayer," he said.
When Smith accepted his Oscar, he referred to Washington's words.
"Denzel said to me a few minutes ago, 'At your highest moment, be careful. That's when the devil comes for you,'" Smith said.
Although he apologised to the academy (but not Rock) as he accepted the award, Smith also appeared to defend his actions and said that "love will make you do crazy things."
He also called Richard Williams - the father of tennis superstars Serena and Venus Williams - a "fierce defender of his family."
