Unstable as water, you shall not excel; because you went up to your father's bed; then you defiled it: he went up to my couch.
All Commentaries on Genesis 49:4 Go To Genesis 49
Hippolytus of Rome
AD 235
He said “couch” and “bed,” that is, the holy flesh of Christ, on which the saints are saved while enjoying their rest as on a holy divan. This is the flesh that those outlaws took possession of and then outraged by offering him [Christ] vinegar, by hitting his head with a reed, by flogging him on the back, by spitting on his face, by skinning his cheeks with slaps and by piercing his hands with nails. All these things the impious and unbelieving people did in accordance with the high priests, the scribes and the leaders of the people. That is why the blessed prophet neither has remained silent about their deeds nor wants to be involved in their wickedness and evil decisions. On the contrary, he keeps himself away from their intrigues where such criminal plots are conceived.
