“Any man.” The Hebrew is idiomatic: “a man, a man,” meaning “any man” (cp. Lev. 17:3, 10, 13; 18:6).
“kills.” That is, kills as a sacrifice, not just to eat. This is made clear in the context. This command elevated God because only He could accept the sacrifice, so it had to be made in His presence, and it prevented people from sacrificing to pagan gods in other places. But the Israelites regularly disobeyed this command and sacrificed animals to pagan gods anyway.
