A.T. Robertson Commentary Luke 24:32

"And they said one to another, Was not our heart burning within us, while he spake to us in the way, while he opened to us the scriptures?" — Luke 24:32 (ASV)

Was not our heart burning? (Ουχ η καρδια εμων καιομενη ην; ). Periphrastic imperfect middle.

Spake (ελαλε). Imperfect active, was speaking. This common verb λαλεω is onomatopoetic, to utter a sound, λα-λα and was used of birds, children chattering, and then for conversation, for preaching, for any public speech.

Opened (διηνοιγεν). Imperfect active indicative of the same verb used of the eyes in verse 31.
