Isaiah 31:2

31:2 Yet he too is wise and he will bring disaster;

he does not retract his decree.

He will attack the wicked nation,

and the nation that helps those who commit sin.

Isaiah 49:4

49:4 But I thought, “I have worked in vain;

I have expended my energy for absolutely nothing.”

But the Lord will vindicate me;

my God will reward me.
