Translation:

He said. The speaker often has to be specified.

My father’s house, or, ‘those who live in my father’s house,’ ‘my nearest kin,’ ‘my family.’

(V. 28) Where a more specific term for brothers (see 6.14) is obligatory they may be taken to have been younger brothers and/or of the same parents.

So that they may warn them, often better as a new sentence here, ‘cause him to warn them,’ or, ‘let him (go and) warn them’ (cf. e.g. Sranan Tongo, Tae,’ Good News Translation). Warn them, or more analytically, ‘tell them not to do as I did.’

Lest they … come, or, ‘in order that they … may not come,’ i.e. once they will have died; hence some adjustments may be required, cf. v. 22.

Place of torment, or, ‘place where I (or, we, exclus.) suffer torment/pain.’
