In a close relationship with GOD one of the things HE warned me about, was never to curse anyone! When someone hurts me, HE said just leave them alone. I have seen dangerous things, where GOD has moved by visiting them or their family members with death, dealing with them with ill health, they lose their jobs, all their plans going upside down and many more.
O thou sword of the Lord, how long will it be ere thou be quiet? put up thyself into thy scabbard, rest, and be still. How can it be quiet, seeing the Lord hath given it a charge against Ashkelon, and against the sea shore? there hath he appointed it.
Jeremiah 47:6-7
