And have ye not cast out the priests of the LORD, the sons of Aaron, and the Levites, and have made you priests like the nations of other lands? Even whosoever cometh and filleth his hand with an ox and seven rams, the same is made priest to them that are no Gods.

But the priests were too few, and were not able to slay all the burnt offerings. Wherefore their brethren the Levites helped them till the work was ended, and until the priests were sanctified. For the Levites were purer-hearted to sanctify themselves then the priests.
