'Concealed' in the Bible

I have not hid thy righteousness within my heart; I have declared thy faithfulness and thy salvation; I have not concealed thy lovingkindness and thy truth from the great assembly.

For mine eyes are upon all their ways; they are not hid from my face, neither is their iniquity concealed from mine eyes.

But they understood not this saying, and it was concealed from them, that they should not perceive it; and they were afraid to ask him about this saying.
