In the Middle East, dogs are viewed with disdain. The grounds of comparison may be their inclination to be sneaky, groveling scavengers feeding on the refuse of humanity, including human flesh. God's Word describes the ritual harlot and the sodomite as vile dogs on the lowest echelon of humanity. The wages of a harlot or sodomite would defile any offering. God expects offering to Him to be undefiled, meeting His standards. An example is the Passover lamb, which was to be without blemish. The Israelites were not allowed to use livestock or produce from Gentiles or foreigners as offerings because they were contaminated. The very land metaphorically vomited them out. Consequently, the offerings we produce should emanate from the work of our own hands and not from any ill-gotten gains. When we give an offering, it should come from pure, unsullied motives.
