Psalm 78:2

And he answered and said to them, Because it is given to you to know the mysteries of the kingdom of heaven, but to them it is not given;

All these things spoke Jesus to the multitudes in parables; and without a parable spoke he not to them;

but without a parable spoke he not to them; and, privately, he explained all things to his disciples.

I will open my mouth in a parable: I will utter dark sayings of old:

For this reason I speak to them in parables; because seeing they do not see, and hearing they do not hear, nor understand.

And he answered and said to them, Because it is given to you to know the mysteries of the kingdom of heaven, but to them it is not given;

but without a parable spoke he not to them; and, privately, he explained all things to his disciples.

And he opened his mouth and taught them, saying;

For there is nothing hid that shall not be made manifest, nor any thing concealed that shall not come to light.
