SEV Biblia, Chapter 7:6 Y los sacerdotes estaban sobre sus guardas; y los levitas con los instrumentos de música del SEÑOR, los cuales había hecho el rey David para confesar al SEÑOR, porque su misericordia es para siempre; cuando David confesaba por mano de ellos. Asimismo los sacerdotes tocaban trompetas delante de ellos, y todo Israel estaba en pie.
John Gill's Bible Commentary Ver. 6. And the priests waited on their offices , etc.] Performed them, some in offering sacrifices, others in blowing trumpets, as it may be explained from the latter part of the verse: the Levites also with instruments of music of the Lord, which David the king had made to praise the Lord ; under a divine direction, on which the Levites played to the songs of praise offered to the Lord, and by which they made music sacred to him: because his mercy endureth for ever ; which, as it was the close of their songs of praise, was the cause of them: when David praised by their ministry ; the songs sung being composed by him, and the instruments they played upon being of his invention, and used by his order: and the priests sounded trumpets before them ; or rather over against them, that is, over against the Levites, as they were singing and playing on the instruments of music: and all Israel stood ; while this sacred and delightful service was performing, they both stood up, and stood by the priests and Levites, and joined with them in praising the Lord.
Matthew Henry Commentary God's answer to Solomon's prayer.
--God gave a gracious answer to Solomon's prayer. The mercies of God to sinners are made known in a manner well suited to impress all wh receive them, with his majesty and holiness. The people worshipped an praised God. When he manifests himself as a consuming Fire to sinners his people can rejoice in him as their Light. Nay, they had reason to say, that God was good in this. It is of the Lord's mercies we are no consumed, but the sacrifice in our stead, for which we should be very thankful. And whoever beholds with true faith, the Saviour agonizin and dying for man's sin, will, by that view, find his godly sorro enlarged, his hatred of sin increased, his soul made more watchful, an his life more holy. Solomon prosperously effected all he designed, for adorning both God's house and his own. Those who begin with the servic of God, are likely to go on successfully in their own affairs. It wa Solomon's praise, that what he undertook, he went through with; it wa by the grace of God that he prospered in it. Let us then stand in awe and sin not. Let us fear the Lord's displeasure, hope in his mercy, an walk in his commandments __________________________________________________________________
