Valentine Heart

Similarly, in the Bible, this idea does not emerge in the earliest passages; Genesis 6:5 situates the thoughts of evil men in their hearts, and Exodus 5 through 12 speak repeatedly of the Lord "hardening Pharaoh's heart." By this it is meant that God made Pharaoh resolve not to let the Israelite slaves leave Egypt, in order to bring judgment against Pharaoh and demonstrate his power: "'Go to Pharaoh, for I have hardened his heart and the hearts of his officials so that I may perform these miraculous signs of mine among them'" (Exodus 10:1). In the Book of Jeremiah 17:9, it is written that the Lord is the judge who "tries" the human heart.
The Sacred Heart of Jesus and the Immaculate Heart of Mary are traditional Roman Catholic devotional images.
