Isaiah 59:2 (KJV)

Context from Isaiah 59

1

Behold, the LORD’s hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear:

2

But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.

3

For your hands are defiled with blood, and your fingers with iniquity; your lips have spoken lies, your tongue hath muttered perverseness.

4

None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity.
