'Irresponsibly' in the Bible

But we command you, brothers, in the name of our Lord Jesus Christ, [that] you keep away from every brother who lives irresponsibly and not according to the tradition that they 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] some among you are living irresponsibly, working [at] nothing, but being busybodies.
