Psalm 47 -- (Read seven times on Rosh Hashanah according to Jewish custom)To the chief Musician, A Psalm for the sons of Korah.
O clap your hands, all ye people; shout unto God with the voice of triumph. For the LORD most high is terrible; he is a great King over all the earth. He shall subdue the people under us, and the nations under our feet. He shall choose our inheritance for us, the excellency of Jacob whom he loved. Selah. God is gone up with a shout, the LORD with the sound of a trumpet. Sing praises to God, sing praises: sing praises unto our King, sing praises. For God is the King of all the earth: sing ye praises with understanding. God reigneth over the heathen: God sitteth upon the throne of his holiness. The princes of the people are gathered together, even the people of the God of Abraham: for the shields of the earth belong unto God: he is greatly exalted.
And then look what Paul says:
1 Corinthians 15:51-52 - Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1 Thessalonians 4:16 - For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
Paul was aware of this Psalm and its themes of ressurrection associated with Rosh Hashanah and its reading on Rosh Hashanah--the Feast of Trumpets. I share this because I had overlooked this aspect myself.
