Commentaries:
The holy days and their offerings are shadows of good things to come (Hebrews 10:1). The offerings especially are indicative of many aspects of Christ's conduct and attitudes while serving God. We are to imitate Him (I John 2:6). Understood correctly, they represent the spiritual manner in which we are to observe these days.
Numbers 28:16—29:40 lists all the offerings to be made at the feasts. One can quickly see that more offerings were required for the Feast of Tabernacles than all other festivals combined. This ought to indicate what God expects regarding our conduct during the Feast of Tabernacles. He requires that we offer ourselves as living sacrifices so that it be most fruitful spiritually. It should be both a spiritual and physical feast whose fruit is rejoicing and learning to fear God as a result of the sacrifices done with understanding and a good attitude. This cannot be forced. It is the fruit of a right approach and use.
