Genesis 25:19

Isaac] 'In Genesis Isaac appears throughout as the pale copy of his father. He is the son of promise and inherits his position, and the possessions and the blessings won by his father. He follows in Abraham's footsteps without his strength of character and purpose. In quietness and patience he faithfully preserves his inheritance, serves his father's God, and in turn like Abraham is guided, preserved, and blessed by him' (D.).
