Matthew 27:11-50
All 4 of the Gospels spend more time telling about the last week of Jesus' life than about any other part of it. The Gospel of Matthew especially emphasizes that Jesus is Israel's King and Messiah, but that the Messiah suffers and dies on the Cross.
Luke 23:32-49
700 years before Jesus died, Isiah wrote that "He was numbered with the transgressors." This prediction was literally fulfilled when Jesus was crucified between 2 criminals.
Acts 14:1-23
Toward the end of their first Missionary Journey, Paul and Barnabas re-visited the churches they had established and appointed Elders in each church.
Colossians 2:6-15
The word "crucified" makes us think of Jesus, but He wasn't the only Jew who was crucified in ancient Palestine. What set him apart from the others is that on the 3rd day, He was raised.
1 Corinthians 1:10-2:5
There is tremendous hostility against the Cross today, not just as a religious symbol, but against the whole idea of Jesus' Death as the way of Salvation. It was the same in Paul's time.
