“Please listen to me,” Laban replied. “I have become wealthy, for the Lord has blessed me because of you.” – Genesis 30:27
On the other side of the coin, let’s remember too that when Abraham travelled with Sarai and twice gave her away to the kings of the land, the land was cursed until she was returned to Abraham. So in one way, Abraham blessed the land by taking her back and praying for God to restore the land and its people.
More directly though we can see the blessing of presence with Sodom and Gomorrah. Abraham rescued the cities earlier and then when God was ready to judge, Abraham stepped in and asked for them to be spared.
However, nothing speaks of blessing better than the life and presence of Joseph. Like Abraham, Isaac and Jacob before him, the incredible productivity of Joseph’s work caused watching foreigners to conclude that God’s presence with Joseph had brought a surprising abundance.
God gave Joseph an interpretation of a dream that predicted a seven-year famine. As the final year of the famine came, he had arranged for the survival of the people of Egypt. In exchange for state ownership of land and a 20% tax, he offered grain to be used as seed for planting as a way of restarting agricultural cycles after the famine.
