'Incurable' in the Bible

"The LORD will afflict you with incurable boils on your knees and legs, and from the sole of your foot to the top of your head.

After all of this happened, the LORD struck him in his bowels with an incurable illness.

Have I lied concerning the justice that I deserve? My wound is incurable, though transgression cannot be attributed to me.'

Incurable sorrow has overwhelmed me, my heart is sick within me.

Why is my pain unending and my wound incurable, refusing to be healed? You are like a deceptive brook, whose waters cannot be depended on.

"The heart is more deceitful than anything. It is incurable who can know it?
