In response to God's promise, Jacob makes a conditional vow that he will return to Bethel and sacrifice a tenth of all that he has. This vow is fulfilled in Genesis 35, as Jacob is returning to his father's house more than 14 years later. He builds an altar and sacrifices to the Lord. I assume he offered a tenth of all his possessions, or flocks. That probably took a long time.

I am sure that Jacob took the time to relate to his family the story of Bethel and how God had revealed himself. The fulfillment of his vow became a testimony of God's faithfulness and surely must have had an impact on his family.

I believe it is very important that we pass on the testimony of what God has done in our lives and family to our children, grandchildren, and great-grandchildren as long as the Lord gives us breath.

Genesis 28:1
