Head
The head is the part of us that is highest, which means in a representative sense that it is what is closest to the Lord. Because of this the head represents what is inmost in us, the thing at the center of our being. In most cases this means intelligence and wisdom, since most of us are in a state of life in which we are led by our thoughts and reason. In the case of the Lord, however, it often represents His perfect love. And in many cases the head is used to represent the whole person.

Arcana Coelestia # 432
432. Verse 24 For sevenfold will Cain be avenged, and Lamech seventy-sevenfold.
This means that men annihilated the faith meant by 'Cain', which it was utterly forbidden to violate; that at the same time they annihilated charity, which born by means of faith, something even more inviolable; and that on account of this, condemnation followed, which is 'being avenged seventy-sevenfold'.
