Psalm 150:6 (ESV) …. “Let everything that has breath praise the Lord! Praise the Lord!”
Let everything that has breath praise the Lord! Even the brute creatures, as in a preceding psalm; but more especially man, in whom God has breathed the breath of life, and is become not only a living but a rational soul; and more especially spiritual men, converted persons, whether Jews or Gentiles; on whom the Spirit of the Lord has breathed, and whom he has quickened; and who breathe in prayer after divine things; and who also have abundant reason to bless and praise his name for what he has bestowed upon them, and has in reserve for them; and for which they should praise him as long as they have breath; see Rev. 5:13.
Praise ye the Lord; all before mentioned, and in the manner as directed, and that in time and to all eternity. Thus ends the book of Psalms. There is another psalm added in the Septuagint, Syriac, Arabic, and Ethiopic versions, and in the metaphrase of Apollinarius; but is owned to be a supernumerary one, and not to be found in all copies; and is said to be written by David, when he fought with Goliath, and conquered him, and is as follows.
Ver. 1. I was little among my brethren, and a youth in my father’s house; I fed my father’s sheep. Ver. 2. My hands made (or used) the organ; and my fingers fitted (or played on) the psaltery or harp: Ver. 3. And who hath declared to my Lord? he is Lord, he hath heard. Ver. 4. He sent his angel, and took me from my father’s sheep; and anointed me with the oil of his anointing, Ver. 5. My brethren were goodly and great; and the Lord delighted not in them. Ver. 6. I went forth to meet the stranger (the Philistine), and he cursed me by his idols: Ver. 7. And I threw at him three stones into his forehead, by the power of the Lord, and laid him prostrate. Ver. 7. I drew out the sword from him; I cut off his head, and took away reproach from the children of Israel.[1]
