28:23 In the morning - And that in the evening too, as is evident from other scriptures; but the morning - sacrifice alone is mentioned, because the celebration of the feast began with it, and principally because this alone was doubtful, whether this might not be omitted when so many other sacrifices were offered in that morning, whereas there was no question but the evening sacrifice should be offered, when there were none other to be offered.
28:16-31 By the sacrifices enjoined in this chapter, we are reminded of the continued power of the sacrifice of Christ, and of our continual need to depend thereon. No hurrying employments, or perilous situations, or prosperous circumstances, should cause slackness in our religious exercises; but should rather stir us up to greater diligence in seeking help from, or giving thanks to the Lord. And all is to be accompanied with repentance, faith is the Lord Jesus, and love to him, and to produce true holiness in our conduct towards all men; otherwise God will abhor our most solemn services and abundant devotions. And Christ is able to supply the wants of every day, every week, every month, every year, every ordinance, every case.
