Translation:
V. 45 expresses a suppositional case: ‘but suppose now…’; v. 46 is to be introduced then by a consecutional connective, e.g. ‘so, then’ (Trukese).
Says to himself, or ‘says in his heart,’ ‘thinks.’
My master is delayed in coming, or, describing the verb, ‘my master does not come (home) quickly/shortly, or, stays away fairly long’; or, ‘it will take a long time before my master returns.’
Beat, probably with hand or stick.
Menservants and maidservants, or, ‘servants, both men and women.’
To eat and drink and get drunk here refers to feasting. In Chuukeseexcessive eating and drinking is expressed by reduplicated forms of the verbs, and “get drunk” by ‘become-foolish.’
(V. 46) On a day when he does not expect him, or, ‘does not await him, or, does not think he will come.’
At an hour he does not know closely parallels the preceding phrase, using a more specific indication of time, and a verb that, in this context, is rather synonymous with ‘to expect.’ Hence the two phrases can better be combined in some languages, cf. e.g. ‘at a day and an hour that are not to-be-known’ (Balinese), ‘at an hour when his heart is forgetful, and he is not expecting him.’
Will punish him, preferably, ‘will punish him by death (or, very severely)’; or in languages that prefer to make explicit indirect agency, ‘will have him punished (or, will order someone to punish him) severely/by death.’
Put him with the unfaithful (preferably, ‘the unbelievers’), or, ‘put him where the unbelievers are, or, in the same place as the unbelievers,’ ‘let him suffer what the unbelievers suffer.’ The term ‘unbelievers,’ i.e. those who do not believe in the God of Israel, refers to the non-Jews in general; hence some versions render ‘heathen’ (Bible de Jérusalem, Bahasa Indonesia). For ‘to believe’ cf. the references on “faith” in 5.20; for ‘heathen’ cf. on “Gentiles” in 2.32.
