Isaiah 1:15

1:15 When you spread out your hands in prayer,

I look the other way;

when you offer your many prayers,

I do not listen,

because your hands are covered with blood.

Isaiah 41:17

41:17 The oppressed and the poor look for water, but there is none;

their tongues are parched from thirst.

I, the Lord, will respond to their prayers;

I, the God of Israel, will not abandon them.
