Isaiah 27:11

27:11 When its branches get brittle, they break;

women come and use them for kindling.

For these people lack understanding,

therefore the one who made them has no compassion on them;

the one who formed them has no mercy on them.

Jeremiah 18:23

18:23 But you, Lord, know

all their plots to kill me.

Do not pardon their crimes!

Do not ignore their sins as though you had erased them!

Let them be brought down in defeat before you!

Deal with them while you are still angry!

Mark 3:29
