In Genesis 28, Isaac blesses Jacob and instructs him not to marry a Canaanite woman, sending him to Paddan-Aram to find a wife. During his journey, Jacob dreams of a ladder reaching to heaven, where God reaffirms the covenant made with Abraham and promises to be with Jacob. Jacob recognizes the significance of the place, names it Bethel, and vows to serve God if he is kept safe and provided for.
