Here are a few translations of Psalm 104:3b-4 to consider. They follow on after verse 1 -Bless the Lord, O my soul! (v1):
who walks on the wings of the wind, Who makes His angels spirits, His ministers a flame of fire. (NKJV)
Who walks on the wings of the wind, Who makes winds His messengers, flames of fire His ministers. (Heb. 1:7) (AMP)
(You) took off on wind-wings. You commandeered winds as messengers, appointed fire and flame as ambassadors. (The Message)
You fly upon the wings of the wind! You make Your messengers into winds of the Spirit, and all your ministers become flames of fire! (TPT)
(You) ride on the wings of the wind. You use the winds as your messengers and flashes of lightning as your servants. (TEV)
