And he answering said to them, Because to you it is given to know the mysteries of the kingdom of the heavens, but to them it is not given;

And he said, To you it is given to know the mysteries of the kingdom of God, but to the rest in parables, in order that seeing they may not see, and hearing they may not understand.

Let a man so account of us as servants of Christ, and stewards of the mysteries of God.

For he that speaks with a tongue does not speak to men but to God: for no one hears; but in spirit he speaks mysteries.
