to make unclean, to defile, to profane to cause something to become unclean, profane, or ritually unacceptable In a number of languages it is quite impossible to translate literally the concept of unclean, for physical cleanliness and ritual acceptability are completely unrelated. In some languages it is necessary to translate κοινόω[a] or βεβηλόω as to take away its holiness or to make something unacceptable to God. In many cultures one must express this concept as involving so-called negative taboo.

1 βεβηλόω may differ significantly from κοινόω[a] in denoting a more serious degree of defilement, but this cannot be readily determined from existing contexts.
