As concerning who the Israelites tempted in the wilderness, 1 Corinthians 10:9 identifies Christ, Hebrews 3:7-9 identifies the Holy Ghost, Psalm 95 identifies Jehovah.
Christ prays to the Father, while also saying He is one with the Father.
Whichever way you harmonise these facts will lead you to upholding the Godhead.
