'Hostility' in the Bible

For He is our peace, who made both groups one and tore down the dividing wall of hostility. In His flesh,

He did this so that He might reconcile both to God in one body through the cross and put the hostility to death by it.

For consider Him who endured such hostility from sinners against Himself, so that you won’t grow weary and lose heart.

Adulteresses! Don’t you know that friendship with the world is hostility toward God? So whoever wants to be the world’s friend becomes God’s enemy.
