Note what is in store for the leaders of nations and those that follow them that set themselves against God and His commandments. “He will speak to them in his wrath and terrify them in his fury.”

“Why do the nations rage, and the people’s plot in vain? The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed (Saints), saying, Let us burst their bonds apart and cast away their cords from us. He who sits in the heavens laughs: the Lord shall have them in derision. Then He will speak to them in his wrath and terrify them in his fury. As for me, I will set my King on Zion, my holy hill. I will declare the decree: The Lord said to Me, You are my Son; this day have I begotten thee. Ask of me, and I shall give you the nations for your inheritance, and the ends of the earth for your possession. You shall break them with a rod of iron and dash them in pieces like a potter’s vessel. Now, therefore, O’ kings be wise: be warned O’ rulers of the earth. Serve the Lord with fear, and rejoice with trembling. Kiss the Son, lest He is angry, and you perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in Him. Psalms 2: 1-12

This cannot be about King David as he never ruled the ends of the earth, nor did he or any of his sons ever enjoy unrivaled control over all the nations. David endured a constant state of warfare until the end of his life. It only makes sense to conclude that it is the Messiah himself, Jesus who is receiving his inheritance from God the Father in these verses, which he will possess when he establishes the Messianic Kingdom in the future.
