Luke 6:22

Separate you. Thought by some to be a reference to excommunication from the synagogue (see John 9:22, 34; 12:42; 16:2). Excommunication might be either permanent, involving complete exclusion from Judaism for all time, or merely temporary. In the time of Christ temporary excommunication lasted for a period of thirty days, during which the person thus “separated” was not only deprived of participation in religious ritual, but was not supposed to come within 4 cubits (about 7 ft.) of another person. Excommunication thus implied both religious and social contamination, or uncleanness.

See Jerusalem Talmud Mo’ed Katan 3.81c.50, cited in Strack and Billerbeck, Kommentar zum Neuen Testament, vol. 4, p. 299.

Cast out your name. That is, throw it away contemptuously. This refers to the circulation of false and malicious reports (see 1 Peter 4:14).

Son of man’s. See on Mark 2:10.
