In one case we have a paradox (very commonplace occurrences throughout nature and culture) and in the other two we have a contrast. Since a very long time ago, I understood these things - as a quite slow infant. So did secular agnostics around me. Your own elders and betters prevailed on you to obey them in abandoning critical thinking!
Why are you repeating these when I already addressed them earlier?
Back to David allegedly killing Goliath twice as you believe, I have the following evidence to deal with:
1. The verses you cite do not stated that David killed Goliath twice. It may be suggested, but it is not stated.
2. There is no apparent reason for God to have David kill Goliath twice.
3. Had David killed Goliath twice, this miraculous event would surely be repeated again in the word of God, but it is never mentioned.
4. There is a feasible interpretation of it as an alternative.
You may claim to be a critical thinker, but I follow the evidence. Based on the evidence here, I can safely conclude that it is a simple interpretation/scribe anomaly that you want to believe is a serious contradiction. Like I said, all apparent contradictions in the word of God can be resolved through the word of God. In addition, if you want to focus on apparent contradictions, please provide New Testament examples because that has been my focus--except for Daniel prophecy because without Daniel, Revelation cannot be solved and explained.
