Then the Samaritan woman said to him

The word "him" refers to Jesus.

How is it that you, being a Jew, are asking me, being a Samaritan woman, for something to drink?

This remark appears in the form of a question to express the Samaritan woman's surprise that Jesus asked her for a drink. Alternate translation: "I cannot believe that you, being a Jew, are asking me, a Samaritan woman, for a drink!" (See: rc://en/ta/man/jit/figs-rquestion)
