Arcana Coelestia #406
406. 'Lamech' means vastation, that is, the fact that faith is no more. This becomes clear from verses 23-24, below, which state that 'he killed a man (vir) to his wounding, and a little one to his bruising'. At that point 'man' is used to mean faith, 'a little one' or little child to mean charity.
Psalms 132:13-14
13
For Yahweh has chosen Zion. He has desired it for his habitation.
14
"This is my resting place forever. Here I will live, for I have desired it.
