Exo. 34:7 teaches that there will be a propensity toward either righteousness or sin being passed down from genration to generation. In different areas of life, people are blessed & do well because of Godly family influences. In other areas they struggle because of evil family influences. Chains of bitterness, dishonesty, selfishness, pride, divorce, immorality, laziness, or rebellion pass down from grandfather to father to son to grandson, etc. Loyalty, faithfulness, kindness, honesty, joy, character, etc. also pass down! King Asa saw a curse of bitterness, stubbornness, rebellion, & idolatry in his family lineage & took desperate steps to break the curse & begin a lineage of blessings!
