Did Jesus Ever Experience Fear?

Questions about whether Jesus ever experienced fear, why Jesus would pray three times for something he already knew he would be denied, and a song that seems to state that Jesus paid the price for all in the garden of Gethsemane rather than on the cross.  

• Jesus came to earth and experienced the same things we go through—hunger, thirst, weariness, anger, sorrow, etc.—but did he ever experience fear?
• Why did Jesus pray three times, “Let this cup pass from me,” when he already knew he would die?
• I recently heard the song “Gethsemane,” which seems to state that Jesus paid the price for all in Gethsemane and doesn’t mention the cross. This feels off, but how can I explain why it matters?
