Our Hebrew word of the week (המילה העברית של השבוע) is kadash ("to sanctify"), taken from the weekly Torah portion called Kedoshim (קדשׁים). Derivatives of this word appear in the second verse of the Torah portion (i.e, Leviticus 19:2):
Kadash is a root word(Strong# 6942; TWOT # 1990) that means to set apart, to distinguish, to sanctify, or to hallow. Kadash connotes that which belongs to the sphere of the sacred, and thus is distinguished from the common or profane. Other words that use this root include:
