I came to bring, not peace, but a sword
Matthew 10
34 Do not think I came to bring peace to the earth; I came to bring, not peace, but a sword. 35 For I came to cause division, with a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law. 36 Indeed, a man’s enemies will be those of his own household.
