'Veiled' in the Bible

Meanwhile, the king veiled his face and kept on crying loudly, "My son Absalom! Absalom my son, my son!"

Tell me, you whom I love, where do you graze your flock? Where do you make your flock lie down at noon? Why should I be considered a veiled woman beside the flocks of your companions?

So if our gospel is veiled, it is veiled to those who are dying.
