Charles Ellicott Commentary Matthew 26:2

"Ye know that after two days the passover cometh, and the Son of man is delivered up to be crucified." — Matthew 26:2 (ASV)

After two days is the feast of the passover — Assuming the Last Supper coincided with the actual Passover feast (as the facts of the case suggest, though see the notes on John 13:1), then these words were spoken at one of two possible times. It could have been sometime on what we would call Tuesday evening of Passion Week. Alternatively, following the Jewish way of speaking which counted three days in the interval between our Lord’s burial and resurrection, it could have been on the morning or afternoon of Wednesday.
