Genesis 48:4

Possession. He makes mention of this first vision of God to him, to shew that he had a right to Chanaan, and to adopt the two children of Joseph, who were each to have as much as his own children. (Haydock) --- Jacob's posterity enjoyed that land till the Messias came, with some few interruptions. But his spiritual children inherit a much better country, (of which this was a figure) an eternal kingdom in heaven. (Calmet)
