And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness,.... Which, according to the law of Moses, were always to follow the passover, Exodus 12:18.
and the Levites and the priests praised the Lord day by day, singing with loud instruments unto the Lord; or instruments of strength (t); 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 Psalm 8:2 compared with Matthew 21:16, the priests blew with trumpets, and the Levites played on harps, psalteries, &c. and this they did every day when the sacrifices were offered, during the seven days of unleavened bread.

Many prayers were put up to God with the peace-offerings. In these Israel looked to God as the God of their fathers, a God in covenant with them. There was also abundance of good preaching. The Levites read and explained the Scriptures. Faith cometh by hearing, and true religion preaching has abounded. They sang psalms every day: praising God should be much of our work in religious assemblies. Having kept the seven days of the feast in this religious manner, they had so much comfort in it, that they kept other seven days also. This they did with gladness. Holy duties should be done with holy gladness. And when sinners humble themselves before the Lord, they may expect gladness in his ordinances. Those who taste this happiness will not soon grow weary of it, but will be glad to prolong their enjoyment.

the children of Israel . . . kept the feast--The time appointed by the law for the continuance of the feast was seven days [Exodus 12:15; Exodus 13:6; Leviticus 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.

And the Israelites that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness; and the Levites and priests praised the Lord day by day, singing to the Lord ליהוה עז בּכלי, "with instruments of power to the Lord," i.e., with which they ascribed power to the Lord; or, to express it more clearly, which they played to the praise of the power of the Lord. The stringed instruments played by the Levites, and the trumpets blown by the priests, to accompany the psalm-singing, are meant. The singing of praise in connection with the sacrificial service took place on the seventh day of the feast.
