Book of Matthew - Chapter 5 - Verse 27

When Jesus said "Ye have heard that it was said by them of old time, Thou shalt not commit adultery," he was referring to the Old Testament commandment found in Exodus 20:14. This commandment was given by God to the Israelites through Moses as part of the Ten Commandments. Adultery, in this context, refers to the act of sexual relations between a married person and someone who is not their spouse. Jesus was not simply repeating this commandment, but was also giving deeper insight into its meaning. He was emphasizing that it is not just the physical act of adultery that is sinful, but also the intentions and desires of the heart that lead to such actions. Jesus taught that even looking at someone with lustful intent is a form of adultery in the heart. By expanding the meaning of this commandment, Jesus was teaching his followers about the importance of purity and faithfulness in relationships, both physical and emotional.

The theological interpretation of the verse "Ye have heard that it was said by them of old time, Thou shalt not commit adultery:" delves into the significance of the commandment against adultery in the Old Testament. Adultery was not only considered a violation of the marital covenant but also a spiritual offense against God. In the broader context of the Sermon on the Mount, Jesus emphasizes the importance of not only outward actions but also the intentions and attitudes of the heart. By highlighting the root causes of sin, Jesus challenges his followers to strive for purity in thought as well as deed. The word studies surrounding adultery shed light on the gravity of this transgression in biblical times, underscoring the importance of faithfulness and loyalty in relationships. This verse serves as a reminder of the timeless moral principles embedded in the scriptures, urging believers to uphold the sanctity of marriage and embody God's design for human relationships.
