John Lightfoot on John 16:13

[Whatsoever he shall hear, that shall he speak.] And verse 14, he shall receive of mine. He speaks according to the dialect and custom of the nation, and so to the capacity of his auditors: If they have heard, they teach: it is spoken of a judge in the lower Sanhedrim consulting a higher court, first, that of the triumvir: and if they hear, they teach; if not, then he goes to the supreme court of all.

The latter clause, he shall receive of mine, seems taken from Isaiah 11:2. And it should seem he inclined rather to this sense, because he does not say, he shall receive of mine and give; but he shall receive and shew it unto you: by which the Jew would understand he shall receive of my doctrine, or from my instructions. For the Holy Spirit is sent as an instructor from the Son, as the Son is sent as a Redeemer from the Father.
