Grieving Heart

1 Samuel 2:33
Every one of you that I do not cut off from my altar will be spared only to blind your eyes with tears and to grieve your heart, and all your descendants will die in the prime of life.

This sad prophecy was for Eli. After Samuel arrived on the scene, and unnamed man of God gave the old priest the bad news. He had so failed to train his sons that God could not allow them anywhere near the tabernacle. His failure wouldn't get a slap on the wrist, but would result in the loss of his family. And not just the two wicked sons but the whole family, forever.
Most would die, as Hophni and Phineas did. Any who lived would know only sadness, weeping, and grief.
Here the innermost self is grieved. This is deep, literally heart-felt sadness, resulting from tolerating sin past the point of turning back. Grief with no consolation.
God keep me from that sin, and that grief.
