In order that the whole  Torah, the five books of Moses, would be read in the course of a year Jewish tradition divides it into weekly sections, "parashot". It is customary to read and reflect on the week's parasha (singular form of "parashot"). Rabbis and others often develop a drash (exegesis/commentary) based on it, sharing a teaching they deduce from the Torah's texts. Last week I delivered a five minute long drash at the beginning of a meeting.
