How to Get the User with Guild. Members. Get()?

I'm having some troubling getting a user to add a role to.

const DonatorAdd = (client, message, args, m_db, m_default, config, moment, server) => {
  var guild = message.guild.id;
  var member = guild.members.get(args[1]);
        if (!member.roles.has('590384740989796392')){ member.addRole('590384740989796392').catch(console.error); }
        if (!member.roles.has('605482684625453056')){ member.addRole('605482684625453056').catch(console.error); }
        if (!member.roles.has('605482688316440599')){ member.addRole('605482688316440599').catch(console.error); }
}

All I get is this error:

"TypeError: Cannot read property 'get' of undefined" on "var member = guild.members.get(args[1]);"

And args[1] is really an ID.
