'Betrays' in the Bible

All because of the many acts of prostitution of [Nineveh] the prostitute,The charming and well-favored one, the mistress of sorceries,Who betrays nations by her acts of prostitution (idolatry)And families by her sorceries.

After a little while the bystanders came up and said to Peter, “Surely you are one of them too; for even your [Galilean] accent gives you away.”
