I'm trying to get the last message of a specific channel but I've couldn't do that, I want that if i write a mand in another channel (Channel 1) that mand gives me the last message of another channel (channel 2).

My code is:

client.on('message', (message)=>{
    if(message.channel.id === '613553889433747477'){
        if(message.content.startsWith('start')){

                message.channel.fetchMessages({ limit: 1 }).then(messages => {
                    let lastMessage = messages.first();
                    console.log(lastMessage.content);
                  })
                  .catch(console.error);
        }
    }
    });

I cleaned up you code a bit, and added some ments explaining what is happening.
If you have more questions, i would remend visiting the official Discord.js Discord server.
https://discord.gg/bRCvFy9

client.on('message', message => {

  // Check if the message was sent in the channel with the specified id.
  // NOTE, this defines the message variable that is going to be used later.
  if(message.channel.id === '613553889433747477'){
    if(message.content.startsWith('start')) {

      // Becuase the message varibable still refers to the mand message,
      // this method will fetch the last message sent in the same channel as the mand message.
      message.channel.fetchMessages({ limit: 1 }).then(messages => {
        const lastMessage = messages.first()
        console.log(lastMessage.content)
      }).catch(err => {
        console.error(err)
      })
    }
  }
})

If you want to get a message from another channel, you can do something like this.
And use the mand start #channel

client.on('message', message => {

  // Check if the message was sent in the channel with the specified id.
  if(message.channel.id === '613553889433747477'){
    if(message.content.startsWith('start')) {

      // Get the channel to fetch the message from.
      const channelToCheck = message.mentions.channels.first()

      // Fetch the last message from the mentioned channel.
      channelToCheck.fetchMessages({ limit: 1 }).then(messages => {
        const lastMessage = messages.first()
        console.log(lastMessage.content)
      }).catch(err => {
        console.error(err)
      })
    }
  }
})
