'Incurable' in the Bible

Withhold thy foot from being unshod, And thy throat from thirst, And thou sayest, 'It is incurable, No, for I have loved strangers, and after them I go.'

Why hath my pain been perpetual? And my wound incurable? It hath refused to be healed, Thou art surely to me as a failing stream, Waters not stedfast.

Crooked is the heart above all things, And it is incurable -- who doth know it?

And they have said, It is incurable, For after our own devices we do go, And each the stubbornness of his evil heart we do.

For thus said Jehovah: Incurable is thy breach, grievous thy stroke,

What! -- thou criest concerning thy breach! Incurable is thy pain, Because of the abundance of thy iniquity, Mighty have been thy sins! I have done these to thee.
