Genesis 33:20

And he erected there an altar, and called it Elelohe Israel (God, the God of Israel). That was Jacob's confession after the many years of travel and sojourn in strange countries: The strong God is the God of Israel. He had experienced the mighty power of God in numerous instances, and was thankful for the days of peace and rest which he now enjoyed. For this reason also his worship, which he formally instituted at Shechem, consisted chiefly in proclaiming the name of this true God. In this all believers, who ever and again enjoy the rich blessings of the Lord in wonderful measure, will cheerfully imitate the aged patriarch.
