In the Watchtower publication "Aid To Bible Understanding" p. 1542-1543 (subject: "Spirit") we read:
Not a person . . .
Personification does not prove personality . . .
However, it is not unusual in the Scriptures for something to be personalized or personified that is not actually a person. Wisdom is personified in the book of proverbs (1:20-33; 8-1-36).
Here the Watchtower is attempting to deny the personality of the Holy Spirit.
In the same publication p. 918 (subject "Jesus Christ") we also read:
Wisdom personified
The revelation of this information concerning the Word in the scriptures fits remarkably the description given ar Proverbs 8:22-31.
Here the Watchtower implies (as they do elsewhere) that wisdom personified actually also figuratively represents a real person - Jesus Christ. The Watchtower then uses this with its own translation of Proverbs 8:22 in order to attempt to try to prove that Jesus is a created being (thus denying his deity).
So it appears (according to the Watchtower) that in Proverbs something (wisdom) that is "not actually a person" is being "personified", while at the same time being used "figuatively to represent [a real person] God's firstborn Son".
The following will look at some issues related to this.
