Psalms 10:7

10:7 His mouth is full of curses and deceptive, harmful words;

his tongue injures and destroys.

Psalms 59:12

59:12 They speak sinful words.

So let them be trapped by their own pride

and by the curses and lies they speak!

Psalms 109:17-18

109:17 He loved to curse others, so those curses have come upon him.

He had no desire to bless anyone, so he has experienced no blessings.

109:18 He made cursing a way of life,

so curses poured into his stomach like water

and seeped into his bones like oil.

James 3:10

3:10 From the same mouth come blessing and cursing. These things should not be so, my brothers and sisters.
