Mark 1:16-20 recounts the disciples leaving their nets to follow Jesus — the very 'leaving everything' Peter refers to here.

In Mark 1:18, James and John leave their nets immediately, providing the specific earlier example of the disciples' abandonment.

Matthew 19:27-30 is the parallel account where Peter says the same thing and Jesus promises rewards for those who leave everything.

In Luke 18:28-30, this same exchange is recorded verbatim, confirming Peter's declaration and Jesus' promise of rewards.

In Philippians 3:7-9, Paul counts all things as loss for Christ, mirroring Peter's abandonment of everything for the sake of following Jesus.

In Matthew 4:20, Peter and Andrew leave their nets to follow Jesus—this is the very event Peter refers to in Mark 10:28.

In Matthew 13:46, the merchant sells all he has for one pearl, illustrating the same radical abandon for the kingdom that Peter claims.

Luke 14:33 teaches that disciples must give up everything — a parallel call to the total commitment Peter describes here.
