30:21-27 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.

21-24. the children of Israel … kept the feast—The time appointed by the law for the continuance of the feast was seven days [Ex 12:15; 13:6; Le 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.
