Context, context, context. Who is the author of this psalm? It is David, not Jesus. There are many cases in the Tanakh of men being referred to as Son of God. This does not indicate divinity.
You questioned the verse I provided to indicate through the psalmist David prophecy of what I believe to be Jesus speaking of his Lord, God. This is referring to a begotten Son, the only one God ever had.
Has the rain a father,
or who has begotten the drops of dew? (Job 38:28)
Are these divine drops of dew? The use of 'begotten' does not imply godhood or divinity. And, as I said, it is not refering to Jesus anyway.
