A.T. Robertson Commentary Luke 24:11

"And these words appeared in their sight as idle talk; and they disbelieved them." — Luke 24:11 (ASV)

As idle talk (ως ληρος). Old word for nonsense, only here in the N.T. Medical writers used it for the wild talk of those in delirium or hysteria.

Disbelieved (pistoun). Imperfect active of απιστεω, old verb from απιστος, without confidence or faith in. They kept on distrusting the story of the women.
