As with many common verbs, the meaning of “to say” in the Bible is highly dependent on context. Who is speaking? Who is hearing? What is it about? Is it a command, a message, an apology, instruction? All these things enter into the meaning of “say.” In general, though, “saying” has to do with sharing truth at various levels -- from the most exalted power people can have to perceive the Lord's desires directly to the most basic of orders issued to people at their lowest.

53. As for the Word itself, it does not say in the prophets that they spoke it from the Holy Spirit but that they spoke it from Jehovah, Jehovah Sabaoth, or the Lord Jehovih, since it says that the Word of Jehovah came to me, that Jehovah spoke to me, and very often, Jehovah said and the saying of Jehovah. Since the Lord is Jehovah, then (as already explained [, ]), the whole Word was spoken by him.

So that no one will doubt that this is the case, I want to list the places in Jeremiah alone where it says the Word of Jehovah came to me, Jehovah spoke to me, Jehovah said, and the saying of Jehovah, which are the following: Jeremiah 1:4, 11-14, 19; 2:1-5, 9, 19, 22, 29, 31; 3:1, 6, 10, 12, 14, 16; 4:1, 3, 9, 17, 27; 5:11, 14, 18, 22, 29; 6:6, 9, 12, 15-16, 21-22; 7:1, 3, 11, 13, 19-21; 8:1, 3, 12-13; 9:3, 6-7, 9, 13, 15, 17, 22-25; 10:1-2, 18; 11:1, 6, 9, 11; 12:14, 17; 13:1, 6, 9, 11-15, 25; 14:1, 10, 14-15; 15:1-3, 6, 11, 19-20; 16:1, 3, 5, 9, 14, 16; 17:5, 19-21, 24; 18:1, 5-6, 11, 13; 19:1, 3, 6, 12, 15; 20:4; 21:1, 4, 7-8, 11-12; 22:2, 5-6, 11, 16, 18, 24, 29-30; 23:2, 5, 7, 12, 15, 24, 29, 31, 38; 24:3, 5, 8; 25:1, 3, 7-9, 15, 27, 29, 32; 26:1-2, 18; 27:1-2, 4, 8, 11, 16, 19, 21-22; 28:2, 12, 14, 16; 29:4, 8-9, 19-21, 25, 30-32; 30:1-5, 8, 10-12, 17-18; 31:1-2, 7, 10, 15-17, 23, 27-28, 31-38; 32:1, 6, 14-15, 25-26, 28, 30, 36, 42; 33:1-2, 4, 10-13, 17, 19-20, 23, 25; 34:1-2, 4, 8, 12-13, 17, 22; 35:1, 13, 17-19; 36:1, 6, 27, 29-30; 37:6-7, 9; 38:2-3, 17; 39:15-18; 40:1; 42:7, 9, 15, 18-19; 43:8, 10; 44:1-2, 7, 11, 24-26, 30; 45:1-2, 5; 46:1, 23, 25, 28; 47:1; 48:1, 8, 12, 30, 35, 38, 40, 43-44, 47; 49:2, 5-7, 12-13, 16, 18, 26, 28, 30, 32, 35, 37-39; 50:1, 4, 10, 18, 20-21, 30-31, 33, 35, 40; 51:25, 33, 36, 39, 52, 58.

These are from Jeremiah alone. It says things like this in all the other prophets and does not say that the Holy Spirit spoke or that Jehovah spoke to them through the Holy Spirit.
