unclean

A person who God considers spiritually unacceptable or defiled is spoken of as if the person were physically unclean. See how you translated this in Ezekiel 23:7. (See: rc://en/ta/man/translate/figs-metaphor)

It was the same for both sisters

This refers to how they had both made themselves unclean. Alternate translation: "Both sisters became unclean through their acts of prostitution" (See: rc://en/ta/man/translate/figs-explicit)
