'Strange' in the Bible

And when the Tent of meeting goes forward, the Levites are to take it down; and when it is to be put up, they are to do it: any strange person who comes near it is to be put to death.

And Nadab and Abihu were put to death before the Lord when they made an offering of strange fire before the Lord, in the waste land of Sinai, and they had no children: and Eleazar and Ithamar did the work of priests before Aaron their father.

And give orders that Aaron and his sons are to keep their place as priests; any strange person who comes near is to be put to death.

And those whose tents are to be placed on the east side of the House in front of the Tent of meeting, looking to the dawn, are Moses and Aaron and his sons, who will do the work of the holy place for the children of Israel; and any strange person who comes near will be put to death.

Why is the Lord taking us into this land to come to our death by the sword? Our wives and our little ones will get into strange hands: would it not be better for us to go back to Egypt?

And your little ones, whom you said would come into strange hands, I will take in, and they will see the land which you would not have.

Death overtook Nadab and Abihu when they made an offering of strange fire before the Lord.
