From whom or what Jesus was hiding (afraid of) in the given cases during his ministry?

We know Jesus is not afraid of anybody or anything, but let us consider these scenarios during His ministry. 1. Jesus healing a leper- Mark 1:43-44 >"Jesus sent him away at once with a strong warning: **“See that you don’t tell this to anyone.** But go, show yourself to the priest and offer the sacrifices that Moses commanded for your cleansing, as a testimony to them.” 2. Jesus Heals a deaf and mute man"- Mark 7:36 >**"And He gave them orders not to tell anyone**; but the more He ordered them, the more widely they continued to proclaim it. " 3. Jesus warns disciples- Mark 8:29-30 >“But what about you?” he asked. “Who do you say I am?” Peter answered, “You are the Messiah.” **Jesus warned them not to tell anyone about him.** So here is my question - To whom or what Jesus was hiding/afraid of in these cases?
