Elizaphan ♂ also known as Elzaphan

Elizaphan and Mishael were orded by Moses to carry Nadab and Abihu out of the camp after they had been killed by God.

Elizaphan was the leader of the Kohathites at Moses' time.

Different Names

The NIV translation has two separate people Elizaphan and Elzaphan both sons of Uzziel. Both Uzziel's have to be Korahithes and both are around the same generation. So they almost clearly are the same person. Additionally, the German Luther uses "Elizafan" all the time.

All this leads me to the conclusion, that this is in fact one and the same person.
