ISB ~ John 2 v6

six stone jars:Together holding over 120 gallons of water.

• The purpose of these water jars is outlined in Num 19:11-22, which stipulates that any Israelite defiled by contact with the dead must be purified with water on the third day and then again on the seventh day. Curiously, the Cana miracle takes place on the third day (2:1), which, according to John’s chronology, is also the seventh day. See note on Jn 2:1.

• The first sign performed by Jesus (water into wine) recalls the first sign performed by Moses (the first plague, water into blood, Ex 7:19). Note that wine is called the “blood” of the grape in Hebrew poetry (Gen 49:11; Deut 32:14).
