With the words of David, and of Asaph. — Heb., in the words. This appears to mean that the singing (2 Chronicles 29:28) consisted in chanting Davidic and Asaphite psalms, and it is usually so explained. But the expression “in the words of David and of Asaph” may be compared with “in the words of Jehovah,” 2 Chronicles 29:15, and “in the command of David and Gad the king’s seer,” 2 Chronicles 29:25; and so may be understood to assert merely that the singing was in accordance with the arrangements of David and Asaph. (1 Chronicles 25:1-2; 1 Chronicles 25:9.)
Asaph the seer. — So Heman is called (1 Chronicles 25:5); and Jeduthun (2 Chronicles 25:15).
With gladness. — Literally, unto exultation — i.e., rapturously.
And they bowed their heads. — When the song was ended (2 Chronicles 29:29).
