2 Chronicles 30:21

“And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness, etc.] Which, according to the law of Moses, were always to follow the passover, (<021218>Exodus 12:18,19) and the Levites and the priests praised the Lord day by day, singing with loud instruments unto the Lord; or instruments of strength f130; so called not from the matter of them, or manner in which they were made, but either from the sound of them, as our version, or from the strength and power of God, which they set forth in praise; the Targum is, “with instruments of praise,” and so the word is sometimes used, (see <190802>Psalm 8:2) compared with (<402116>Matthew…”

“the children of Israel . . . kept the feast--The time appointed by the law for the continuance of the feast was seven days [Exo 12:15; Exo 13:6; Lev 23:6]; but in consequence of its having been allowed to fall so long into desuetude, they doubled the period of celebration and kept it fourteen days with unabated satisfaction and joy. Materials for the additional sacrificial meals were supplied by the munificence of the king and the princes.”
