God was displeased with Abraham for not living in peace and harmony with his own kindred, as he lived with all the world beside. On the other hand, God also took it in ill part that Abraham was accepting Lot tacitly as his heir, though He had promised him, in clear, unmistakable words, "To thy seed will I give the land." After Abraham had separated himself from Lot, he received the assurance again that Canaan should once belong to his seed, which God would multiply as the sand which is upon the sea-shore.
As the sand fills the whole earth, so the offspring of Abraham would be scattered over the whole earth, from end to end; and as the earth is blessed only when it is moistened with water, so his offspring would be blessed through the Torah, which is likened unto water; and as the earth endures longer than metal, so his offspring would endure forever, while the heathen would vanish; and as the earth is trodden upon, so his offspring would be trodden upon by the four kingdoms.
