Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts. For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little: For with stammering lips and another tongue will he speak to this people. To whom he said, This is the rest with which you may cause the weary to rest; and this is the refreshing: yet they would not hear. But the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; that they might go, and fall backward, and be broken, and snared, and taken. (Isaiah 28:9-13)

And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead? To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. (Isaiah 8:19-20)

Is there any thing of which it may be said, See, this is new? it has been already of old time, which was before us. (Ecclesiastes 1:10)

He said unto him, What is written in the law? how read you. (Luke 10:26)

And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself. (Luke 24:27)

And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. (John 1:14)

These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. (Acts 17:11)

But God has revealed them unto us by his Spirit: for the Spirit searches all things, yea, the deep things of God. For what man knows the things of a man, save the spirit of man which is in him? even so the things of God knows no man, but the Spirit of God. Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. Which things also we speak, not in the words which man’s wisdom teaches but which the Holy Ghost teaches comparing spiritual things with spiritual. But the natural man receives not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. But he that is spiritual judges all things, yet he himself is judged of no man. For who has known the mind of the Lord, that he may instruct him? But we have the mind of Christ. (1 Corinthians 2:10-16)

And that from a child you have known the holy scriptures, which are able to make you wise unto salvation through faith which is in Christ Jesus. All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, thoroughly furnished unto all good works. (2 Timothy 3:15-17)

For he received from God the Father honor and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased. And this voice which came from heaven we heard, when we were with him in the holy mount. We have also a more sure word of prophecy; Unto which you do well that you take heed, as unto a light that shines in a dark place, until the day dawn, and the day star arise in your hearts: Knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spoke as they were moved by the Holy Ghost. (2 Peter 1:17-21)
