This drawing is a depiction of the stoning of Stephen in Acts.

Acts 7:54-59 (New International Version)
The Stoning of Stephen
 54When they heard this, they were furious and gnashed their teeth at him. 55But Stephen, full of the Holy Spirit, looked up to heaven and saw the glory of God, and Jesus standing at the right hand of God. 56"Look," he said, "I see heaven open and the Son of Man standing at the right hand of God."
 57At this they covered their ears and, yelling at the top of their voices, they all rushed at him, 58dragged him out of the city and began to stone him. Meanwhile, the witnesses laid their clothes at the feet of a young man named Saul.
 59While they were stoning him, Stephen prayed, "Lord Jesus, receive my spirit."

The "hard pressed verse" we added as print to the shirt because we feel it is very relevant to this.

2 Corinthians 4:8 (New International Version)
We are hard pressed on every side, but not crushed; perplexed, but not in despair; 9persecuted, but not abandoned; struck down, but not destroyed.
