When someone comes against you, you are NOT to revenge yourself by harassing them with repeated messages especially if they have told you that they do not want anything to do with you. We are to shut our mouths and keep our hands to our selves. We have no business contacting people who have told us to leave them alone. We are NOT to do anything against them or their family or property. If they truly did us wrong, we are to take it to GOD alone and leave it in HIS Hands.
Isa.53:7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
Acts 8:32 The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth:
1 Peter 3:9 Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.
