What is Reformed Theology/Calvinism 10: What About 2 Peter 2:1 & Matthew 23:37?

Do 2 Peter 2:1 or Matthew 23:37 contradict the teachings of Calvinism like limited atonement or unconditional election? How is Deuteronomy 32:5-6 relevant to the interpretation of 2 Peter 2:1? Is Jesus mourning over the unwillingness of Jerusalem to be gathered or the unwillingness of the spiritual leaders to support Christ's ingathering?
