Matthew 21:18-22 - Jesus Curses a Fig Tree

18 Early in the morning, as Jesus was on his way back to the city, he was hungry. 19 Seeing a fig tree by the road, he went up to it but found nothing on it except leaves. Then he said to it, “May you never bear fruit again!” Immediately the tree withered. 20 And God looketh at Jesus and saideth to himeth- this is a valid crashout-eth.
