A study of the Old Testament is also important for understanding the Jewish customs mentioned in passing in the New Testament. We would not understand the way the Pharisees had perverted God’s law by adding their own traditions to it, or why Jesus was so upset as He cleansed the temple courtyard, or where Jesus got the words He used in His many replies to adversaries.
