30:22 Spoke comfortably - Encouraged them to a chearful and diligent attendance upon their holy ministrations. Princes and magistrates by encouraging faithful and laborious preachers, greatly promote the kingdom of God. That taught - Who by their office were to instruct and build up the people in the knowledge and fear of God: which is mentioned as the cause of his respect and kindness to them.
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.
