Many trinitarians say that the Holy Spirit is identified as a person. They claim that the Bible clearly identifies the Holy Spirit with personable characteristics and therefore demonstrates that the Holy Spirit is indeed a person. While I disagree with the interpretation of the Holy spirit being identified with personal characteristics, personification of the Holy Spirit in itself does not prove the Holy Spirit is in fact as person as personification  is actually prevalent throughout the Bible and does not necessitate that the thing being personified is in fact an identifiable person.

Sin for instance is personified and referred to as a him in Genesis chapter 4

Cain is told, when he became angry, after his offering was rejected by God, that if a person doesn’t do well that sin lieth at the door. Then sin is referred to as a HE when God says that HIS (sins) desire will be you , but you should rule over HIM (sin).

Genesis 4  6And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen? 7If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.

Wisdom is personified 

Proverbs 1- 20 Wisdom crieth without; she uttereth her voice in the streets: 21She crieth in the chief place of concourse, in the openings of the gates: in the city she uttereth her words, saying,

Trees, including specifically identified trees, the Olive tree and the fig tree, plus the vine and bramble are all personified in the book of Judges 

Judges 9- .  8The trees went forth on a time to anoint a king over them; and they said unto the olive tree, Reign thou over us. 9But the olive tree said unto them, Should I leave my fatness, wherewith by me they honour God and man, and go to be promoted over the trees? 10And the trees said to the fig tree, Come thou, and reign over us. 11But the fig tree said unto them, Should I forsake my sweetness, and my good fruit, and go to be promoted over the trees?12Then said the trees unto the vine, Come thou, and reign over us. 13And the vine said unto them, Should I leave my wine, which cheereth God and man, and go to be promoted over the trees? 14Then said all the trees unto the bramble, Come thou, and reign over us. 15And the bramble said unto the trees, If in truth ye anoint me king over you, then come and put your trust in my shadow: and if not, let fire come out of the bramble, and devour the cedars of Lebanon.

Mountains are referred to as singing and trees describes as clapping their hands in Isaiah

Isaiah 55-12 For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands.

Isaiah 44-23 Sing, O ye heavens; for the LORD hath done it: shout, ye lower parts of the earth: break forth into singing, ye mountains, O forest, and every tree therein: for the LORD hath redeemed Jacob, and glorified himself in Israel.

Isaiah 49-13 Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the LORD hath comforted his people, and will have mercy upon his afflicted.

Valleys are described as shouting for joy and singing in a Psalm

Psalm 65-13 13The pastures are clothed with flocks; the valleys also are covered over with corn; they shout for joy, they also sing. 

God warns not to case the land to sin. Can land sin?

Deuteronomy 24-4 Her former husband, which sent her away, may not take her again to be his wife, after that she is defiled; for that isabomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee for an inheritance.

Personification does not prove personhood. The personification of the Spirit does not therefore prove the Holy Spirit is a person of the Godhead.

Please see my writing on the Holy Spirit for a more detailed look into the individual verses used to claim personhood of the Holy Spirit.
