The message, in Kiswahili, said a wild cat should be in the forest and should go back there. He also said he was exhausted.
The short message quickly got attention and caused a lot of guessing on social media.
Many Kenyans think the post is about Marion Naipei, the young woman who became well-known after sharing her problems online a few weeks ago.
When she was getting a lot of attention, Pastor Kanyari publicly offered to support her, no matter what. People praised him for offering help when her story had touched so many.
However, the tone of the new post isn't clear. Some people on social media think the pastor is hinting at being frustrated or disappointed.
Others think the message means he might have backed away from helping her. Some Kenyans are wondering if he is still helping her or if things have changed.
Even with the guessing, Pastor Kanyari hasn't said anything to explain his words or talk about Marion Naipei’s situation.
This has made the online debate even bigger, with strong opinions on both sides. Some want people to wait before making assumptions, while others want him to be clear, because he publicly promised to help her.
As people keep talking about it, the post reminds us that a few words online can cause big reactions and different ideas about what they mean.
Until Pastor Kanyari speaks openly, people will likely keep wondering about his support and what he meant in his late-night post.
