Songfacts®:

• This slow-burning track is a layered opus that features several revelations pertaining to Kendrick Lamar's personal life. The song is a portrait of an artist terrified of his mom, losing his life and failing in his career.
• The song is split into three verses, which find the Compton MC learning to cope with fear at ages 7, 17 and 27. Before the first verse there is a recording of a call from Lamar's bible-fearing cousin Carl Duckworth who refers to the Old Testament book of Deuteronomy. This voicemail is only on the streaming version of the song.
  
  On his track, "Yah," Kendrick references this voicemail and says he's an Israelite. He explains that he identifies the suffering of Black Americans with the trials and tribulations of the Old Testament's Children of Israel.
• The theme of suffering is continued with the bridge, which is voiced by Charles Edward Sydney Isom Jr. It is a cry to God asking why he is cursed. It ends with Lamar speaking in reverse bemoaning "the pain in my heart carrying the burden for the struggle."
• The first verse finds Lamar recalling being a child in fear of his mother.
  
  I beat yo ass if you tell them social workers he live here
  I beat yo ass if I beat yo ass twice and you still here
  Seven years old, think you run this house by yourself?
  Nigga, you gon' fear me if you don't fear no one else
  
  Lamar's mom employed scare tactics to keep her son from getting in trouble around his neighborhood in Compton.
• The second verse finds Lamar looking back at being a teenager afraid that his skin color will "prolly" cost him his life, as he imagines all the ways he might die.
  
  I'll prolly die anonymous
  I'll prolly die with promises
  I'll prolly die walkin' back home from the candy house
  I'll prolly die because these colors are standin' out
  
  Lamar's traumatic upbringing amidst Compton's gang warfare left him believing that dying at 17 is normal.
• The third verse on "Fear." shows Lamar recounting his fear as a 27-year-old newfound star "losing it all."
  
  At 27, my biggest fear was losin' it all
  Scared to spend money, had me sleepin' from hall to hall
  Scared to go back to Section 8 with my mama stressin'
  30 shows a month and I still won't buy me no Lexus
  
  During a 2014 interview with Complex, Lamar talked about how despite carving a successful career in music, he was still in fear of going broke.
  
  "I've got this thing where I'm scared I'ma lose all my money…I be talking to a few of my partners that's doing they thing. A few of them don't feel the same way but it's like a real deal for me. I treat myself every now and then, but for the most part I be wanting to be smart about it. If my music were to stop today, how would I make this stretch for the rest of my life? My kid's lifetime? Hopefully my grandkids. If I stopped today, how would I do that?"
• The slow-burning instrumental backing is supplied by The Alchemist, who co-produced Lamar's 2017 standalone single, "The Heart Part 4". The East Coast beatmaker samples for the track part of 24-Carat Black's "Poverty's Paradise" which has previously been borrowed from for cuts by Yo Gotti, Freeway, and RZA.
• Speaking with journalist Touré for an October 2017 i-D Magazine interview, Kendrick Lamar said this song features what he believes is the greatest lyrical accomplishment of his career to date.
  
  "It's completely honest," he explained. "The first verse is everything that I feared from the time that I was seven years old. The second verse I was 17, in the third it's everything I feared when I was 27. These verses are completely honest."
