Bible Verses About Priests: Teaching the law

To Levi also he said: Thy perfection, and thy doctrine be to thy holy man, whom thou hast proved in the temptation, and judged at the waters of contradiction:

Thy judgments, O Jacob, and thy law, O Israel: they shall put incense in thy wrath and holocaust upon thy altar.

For the lips of the priests shall keep knowledge, and they shall seek the law at his mouth: because he is the angel of the Lord of hosts.
