Deuteronomy warns against false prophets who perform signs, just as Jesus warns against false claims of his presence.

Mark 13:21 is the parallel passage, nearly identical warning about false messiahs.

Luke 17:23 gives a similar warning not to follow those who say 'here he is', in the context of the Son of Man's coming.

Luke 17:24 contrasts secret claims with Christ's visible coming like lightning, explaining why not to believe them.

In Luke 21:8, the same warning appears: many will come claiming 'I am he' — reinforcing Jesus' command not to believe them.

Mark 13:6 is the parallel account: 'Many will come in my name, saying, I am he, and will deceive many' — identical warning.

1 John 4:1 commands testing spirits because many false prophets exist — directly applying Jesus' warning not to believe every claim.

Luke 17:21 uses the same 'look here/there' language, teaching God's kingdom is not located — reinforcing the warning against location-based claims.

John 5:43 explains why false Christs succeed: people accept one who comes in his own name, unlike Jesus who came in the Father's name.
