A.T. Robertson Commentary Luke 24:30

"And it came to pass, when he had sat down with them to meat, he took the bread and blessed; and breaking [it] he gave to them." — Luke 24:30 (ASV)

When he had sat down (εν τω κατακλιθηνα αυτον). Luke's common idiom as in verses 4,15. Note first aorist passive infinitive (on the reclining as to him).

Gave (επεδιδου). Imperfect, inchoative idea, began to give to them, in contrast with the preceding aorist (punctiliar) participles.
