By the Word of the Lord were the heavens established, and all the might of them by the Spirit of His mouth, Who gathereth together as into a wineskin the waters of the sea, Who layeth up the abysses in storehouses. (Psalm 32:6, Boston Sept Translation)
Some translations have "breath of His mouth" – the Holy spirit is also known as "breath" or wind.
This is a Trinitarian reference. There are many more in the Scripture. The Father, Son (Word) and Spirit (breath) are seen to be creating. since creation is an act of will, and God, being one in essence, has one will, all persons of God were equally involved in creation.
