'Strange' in the Bible

And Nadab and Abihu, the sons of Aaron, took their vessels and put fire in them and perfume, burning strange fire before the Lord, which he had not given them orders to do.

And the Lord said to Moses, after the death of the two sons of Aaron when they took in strange fire before the Lord and death overtook them;

Nothing may be used for food with its blood in it; you may not make use of strange arts, or go in search of signs and wonders.

Let him be to you as one of your countrymen and have love for him as for yourself; for you were living in a strange land, in the land of Egypt: I am the Lord your God.

And death will overtake you among strange nations, and the land of your haters will be your destruction.
