1 Chronicles 25:5

The king's seer, or prophet, which is the same thing, 1 Samuel 9:9. Either he was a prophet as well as a singer; or he is thus called because he prophesied in the sense designed, 1 Chronicles 25:1. And he is called the king's seer, either because the king took special delight in him, or because he frequently attended upon the king in his palace, executing his sacred office there, while the rest were constantly employed in the tabernacle. In the words of God, i.e. to sing such Divine songs as were inspired by God to the prophets or holy men of God. To lift up the horn; either,

1. Metaphorically, to extol and praise God for exalting the horn (i.e. the power and kingdom) of David; of which phrase see Psalms 92:10 Psalms 132:17. Or rather,

2. Properly, to praise God with the sound of a trumpet, (as was usual, as 2 Chronicles 5:12, 2 Chronicles 13:12) or some other musical instrument made of horn, which being a martial kind of music, might be most grateful to David's martial spirit; though he was also skilled in other instruments of music, which he used in the house of God, as is expressed in the next verse.
