 Goodacre lists a number of occasions where it appears that Matthew or Luke begin by altering Mark, but become fatigued and lapse into copying Mark directly, even when doing so is inconsistent with the changes they have already made.For example, Matthew is more precise than Mark in the titles he gives to rulers, and initially gives Herod Antipas the correct title of "tetrarch", yet he lapses into calling him "king" at a later verse, apparently because he was copying Mark at that point.Another example is Luke's version of the Parable of the Sower, regarding the seed sown on rocky ground, where Luke omits several elements of the parable, but then follows Mark in the parable's interpretation.
