ISB ~ Acts 9 v43

a tanner:A tradesman who lived in a state of perpetual uncleanness because of his frequent contact with animal skins and carcasses (Lev 5:2). Though association with such people was discouraged among religious Jews, Peter accepts Simon’s hospitality with a new level of openness that anticipates his discovery in the following episode that no man is legally “unclean” in the age of the New Covenant (10:28).
