Who is Wisdom? Proverbs 8:22-31

Proverbs 8:22-31 The LORD brought me forth as the first of his works, before his deeds of old; I was appointed from eternity, from the beginning, before the world began. When there were no oceans, I was given birth, when there were no springs abounding with water; before the mountains were settled in place, before the hills, I was given birth, before he made the earth or its fields or any of the dust of the world. I was there when he set the heavens in place, when he marked out the horizon on the face of the deep, when he established the clouds above and fixed securely the fountains of the deep, when he gave the sea its boundary so the waters would not overstep his command, and when he marked out the foundations of the earth. Then I was the craftsman at his side. I was filled with delight day after day, rejoicing always in his presence, rejoicing in his whole world and delighting in mankind.

Wisdom here is being used as a personification of the character and virtue of wisdom itself. God and Jesus are all-wise (Job 36:5; Psa. 147:5; Prov. 2:6; Isa. 40:28; 55:8-9; Jer. 51:15-17; Dan. 2:20; Rom. 11:33; Col. 2:3; Jam. 1:5). However, this portion of the proverb is concerning a self-praise of wisdom's origin. As Sproul comments:

Wisdom is not a fourth divine person, but an attribute of God that is given expression in creation as well as redemption. In this chapter, wisdom is personified for poetic effect. The attributes of God are eternal, so the figure of wisdom is said to be from the beginning.
