Inspiration is not the same as dictation. It is more subtle. God inspired all the writings of Scripture, but the work is ALSO the work of the human author. Thus, the message God wants sent by the passage is infallibly true for the purpose He wanted it there.
It will NOT be infallibly true for other purposes. Thus, Genesis is not intended to be a science textbook. Instead, it is a poetic description that tells us that God created us by His power for His purposes and it reveals much about our status in the world.
Similarly, in the New Testament God required for witness to be made to the life, teachings and miracles of Jesus. It is simply not important whether peripheral details are slightly askew. That is the effect of the human authors. Ask any cop, a group of eyewitnesses interviewed separately usually WILL produce a clear picture of what happened even though no two accounts match perfectly. So is the case with the gospels, history is related in the way in which it impacted each individual author, which happens to be the way God intended it to speak clearly to thousands of years worth of billions of different human individuals.
Absolutely nothing of substance is in question. It matters not if Jesus fed 5,000 or 4,000 with a few loaves. It matters not if his pubic ministry took him in and out of Jerusalem, or if it built steadily to a single climax there. The events are what counts.
