Day 55- Exodus 29-30

Henry speaks of the consecration of the priests,

Now,(1.) The work to be done was the consecrating of the persons whom God had chosen to be priests, by which they devoted and gave up themselves to the service of God and God declared his acceptance of them; and the people were made to know that they glorified not themselves to be made priests, but were called of God, Heb. 5:4, Heb. 5:5 . They were thus distinguished from common men, sequestered from common services, and set apart for God and an immediate attendance on him. Note, All that are to be employed for God are to be sanctified to him. The person must first be accepted, and then the performance. The Hebrew phrase for consecrating is filling the hand (v. 9): Thou shalt fill the hand of Aaron and his sons, and the ram of consecration is the ram of fillings, v. 22, v. 26. The consecrating of them was the perfecting of them; Christ is said to be perfect or consecrated for evermore, Heb. 7:28 . Probably the phrase here is borrowed from the putting of the sacrifice into their hand, to be waved before the Lord, v. 24. But it intimates, [1.] That ministers have their hands full; they have no time to trifle, so great, so copious, so constant is their work. [2.] That they must have their hands filled. Of necessity they must have something to offer, and they cannot find it in themselves, it must be given them from above. They cannot fill the people’s hearts unless God fill their hands; to him therefore they must go, and receive from his fulness. (2.) The person to do it was Moses, by God’s appointment. Though he was ordained for men, yet the people were not to consecrate him; Moses the servant of the Lord, and his agent herein, must do it. By God’s special appointment he now did the priest’s work, and therefore that which was the priest’s part of the sacrifice was here ordered to be his.

As for the prices, the shekels, that are ordered paid, Henry notes,

Note, Those that have the benefit of God’s tabernacle among them must be willing to defray the expenses of it, and not grudge the necessary charges of God’s public worship. Thus we must honour the Lord with our substance, and reckon that best laid out which is laid out in the service of God.

Oftentimes, I hear people say that they don't like to "pay" to go to church.  I think that the point is that you are not paying to go to church, you are paying so that there is a place to worship God.
