'Irresponsibly' in the Bible

Now we command you, brothers, in the name of our Lord Jesus Christ, to keep away from every brother who walks irresponsibly and not according to the tradition received from us.

For you yourselves know how it is necessary to imitate us, that we did not behave irresponsibly among you,

For we hear that there are some among you who walk irresponsibly, not working at all, but interfering with the work of others.
