Exodus 22:20

New English Translation

²⁰“Whoever sacrifices to a god other than the Lord^[a] alone must be utterly destroyed.^[b]

Exodus 22:20 tn Heb “not to Yahweh.”
Exodus 22:20 tn The verb חָרַם (kharam) means “to be devoted” to God or “to be banned.” The idea is that it would be God’s to do with as he liked. What was put under the ban was for God alone, either for his service or for his judgment. But it was out of human control. Here the verb is saying that the person will be utterly destroyed.
