The Lord expresses His love for Israel, but warns of impending judgment on the priests for their corrupt practices and the people for their unfaithfulness. The priests have polluted God's name by offering lame sacrifices and have broken their covenant with God by marrying foreign women and despising their brothers. The Lord calls His people to return to Him, promising to bless them if they bring their tithes and offerings, and warns that He will judge those who have done evil.
