Jesus is talking to a group of people about what they as individuals should or should not do. All occurrences of "you" and "your" are singular, but in some languages they may need to be plural. (See: [[rc://en/ta/man/jit/figs-you]])
It is implied that this is God's altar at the temple in Jerusalem. Alternate translation: "to God at the altar in the temple" (See: [[rc://en/ta/man/jit/figs-explicit]])
