No internal inconsistency in the Bible. Often more than one discussion about the same topic. The discussions overlap, showing some info that is the same, and other info that is additional to each discussion, and other that is deleted fro each. In other words, some witnesses recall some points while other witnesses recall other points.

At times the Bible seems to talk about something that another part of the Bible seems to talk about differently. The Bible is a writing that does not cover every topic under the sun in detail. It also does not always say when it is talking about two similar points rather than the same point from two different views.

For example, the little bit that we see in the Gospels where Jesus' words are quoted, are certainly not the only things He ever said in His life. We simply do not know whether the things He says in one Gospel were always those things that were recorded in another Gospel, even though they look very similar. They could have been said twice, on different days.
