Genesis 37:4
,NIV“When his brothers saw that their father loved him more than any of them, they hated him and could not speak a kind word to him.”
Context
Jacob openly favored Joseph, and his brothers' jealousy grew into hatred. Scripture is honest that favoritism and jealousy can damage a family deeply.
For your life
Be honest with God about any jealousy you feel toward a sibling. Naming it is the first step to keeping it from growing into bitterness.
