As part of the consecration of Aaron and his sons as high priests, the Lord instructed Moses,
“And you shall take some of the blood that is on the altar, and some of the anointing oil, and sprinkle it on Aaron and on his garments, on his sons and on the garments of his sons with him; and he and his garments shall be hallowed, and his sons and his sons’ garments with him. Also you shall take the fat of the ram, the fat tail, the fat that covers the entrails, the fatty lobe attached to the liver, the two kidneys and the fat on them, the right thigh (for it is a ram of consecration), one loaf of bread, one cake made with oil, and one wafer from the basket of the unleavened bread that is before the Lord; and you shall put all these in the hands of Aaron and in the hands of his sons, and you shall wave them as a wave offering before the Lord. You shall receive them back from their hands and bur n them on the altar as a burnt offering, as a sweet aroma before the Lord. It is an offering made by fire to the Lord” (Exodus 29:21–25).
Aaron and his sons had a very special privilege of serving the Lord, making offerings to Him. Can you picture yourself doing something so privileged and honored? Yet, if you are a Christian, you make offerings to the God of heaven all the time. Therefore, be sure to worship Him regularly, pray endlessly, and give whatever you can.
