Translation:

To dine with him, or ‘to lunch (or, ‘eat at noon,’ ‘take the midday meal’) with him (or, at his house).’ Several versions do not indicate the time of day, “to eat with him” (Good News Translation), ‘to come to his house to eat’ (Toraja-Sa’dan). Cf. also “to eat with” in 7.36.

Went in. If the house has not been referred to already in what precedes, one may have to do so here, ‘entered his house’ (Bahasa Indonesia).

Sat at table, cf. 7.36.
