These rules keep runaway slaves safe and wicked profits out of the house of the Lord. We see the theme of holiness as we have seen in the previous verses. Do not return a slave to his master if he comes to you, if he lives with you, or if he goes wherever he wants to go. Don't abuse or mistreat them. The Israelites must provide a place of safety for the runaway slaves because Israel itself had once escaped from slavery. In the Canaanite religions of the time, temple prostitutes had relationships with worshipers to ensure their fields and flocks were fertile. The gentleman is disgusted by that behavior. No Israelite man or woman may become a temple prostitute and no earnings of a prostitute or prostitute are to be brought into the house of the Lord to fulfill a promise to him because the Lord detests them both. In this case it is about keeping “emphi” earnings out of the church. The church is filled with the presence of God and therefore should have nothing unholy in its walls. If any earnings of a prostitute, woman or man, enter the church and are used to fulfill a promise made to God, it will turn away from him.
