This is a fascinating discovery - excellent! Praise Yah! I have long believed that all 7 Ruachs were somehow involved in the bringing forth of Yah'shua, and this is good evidence.

In confirmation that the Ruach is NOT 7 but just one;
In the Wisdom of Solomon; In praise of Wisdom 7:26-27
She is the brightness that streams from everlasting light, the flawless mirror of the active power of God and the image of his goodness. She is but one, yet can do everyything; herself unchanging, she makes all things new; age after age she enters into holy souls, and makes them God's friends and prophets, for nothing is acceptable to God but the man who makes his home with wisdom.

Here's another way to apprehend the concept: it is not a case of either/or, but rather both/and. The first century Nazarenes believed in One Elohim Family (Father, Son, Mother) while also believing in a multiplicity of Power-Beings (Father, Son Mother(s?)).

Likewise Jacqui, you are right that the Ruach HaQodesh is spoken of most of the time in the singular, However in Zecharyah 4:10; Gilyahna/Revelation 1:4, 3:1, 4:5, 5:6; and now Malachi 2:15 She is spoken of in the plural form. That doesn't mean that the Scriptures are in conflict with one another, but rather it means that all the passages combined together are giving you a more complete picture.

There are things like this that occur in the physical world. For example in quantum physics, Superstring theory had 5 distinct theories but then M-theory was figured out to unify all of them.

Here's an underlying question for an upcoming chapter that might help you grapple with The Ruach HaQodesh being 7 (I admit when i first heard of that concept I was also a bit shook up): Why are believers the temples of the Ruach HaQodesh, but not temples of Abba YHWH? Stay tuned for the answer...(it will be awhile while my brother in law tries to recover my bios-errored hard drive)

Treasures only yield themselves to those who persistently dig. So many baffling scriptural mysteries have been solved by digging deep shafts into the dirt of the Word, and often in the most unexpected places where few bother to look. I can remember the time when I was born again hearing ALL these explanations of who "Elohim" was and getting totally baffled - it was like showing someone a dozen oranges and insisting that there was only one yet somehow there was a 'dozenness' within the imaginary single orange, when really all that needed to be conveyed is that there is only One Orange-Kind just as there is only one Elohim-Kind because there is only one Power that is Elohim and everything else is a derivative.
