Matthew's Use of Mark

The following table shows which Markan pericopes Matthew expands and which ones he condenses. Passages that contain double tradition material are marked with an asterisk. The last two columns shows how many words Matthew took to write what Mark wrote and how many words Luke used to writing something Mark did not write. I have highlighted cells with at least 30 words not taken from Mark. Anything less than this seemed to just be expansions on Mark that did not make use of an extra source, except possibly in the case of the Last Supper, but even there it is not certain that Matthew is using another source (though as Dunn points out you would expect Matthew to have additional knowledge of traditions in key liturgical passages, such as the Lord's Prayer and the Lord's Supper).
