I added the question to the original post.
In Leviticus 10:3-7 there is the episode where the two sons of Aaron (Nadab and Abihu)died when they went into the tabernacle.
Leviticus 10:1-2 (KJV)
1 And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not. 2 And there went out fire from the LORD, and devoured them, and they died before the LORD.
In that circumstance the Aaron remained silent in the first explanation of what had happened in verse 3
3 Then Moses said unto Aaron, This is it that the LORD spake, saying, I will be sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.
In verse 4 the sons of Uzziel who was the uncle of Aaron were instructed to "come near" to God which means they were instructed to enter into the holy of holies to retrieve the bodies.
4 And Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said unto them, Come near, carry your brethren from before the sanctuary out of the camp. 5 So they went near, and carried them in their coats out of the camp; as Moses had said. 6 And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Uncover not your heads, neither rend your clothes; lest ye die, and lest wrath come upon all the people: but let your brethren, the whole house of Israel, bewail the burning which the LORD hath kindled. 7 And ye shall not go out from the door of the tabernacle of the congregation, lest ye die: for the anointing oil of the LORD is upon you. And they did according to the word of Moses.
Commentators are split on what exactly the two sons of Aaron had done. right after this event, God instructed Aaron to prevent anyone from entering into the tabernacle that had drank wine or string drink. Commentators have looked at verses 12-13 to suggest that Aarons sons had gone into the holy of holies in a drunken state and that is why they were killed.
Given this circumstance of an actual event, it was God who instructed someone to take out the bodies so the idea of the rope seems contrary to what we would expect. Entering into the holy of Holies was a wonderful act of worship. The one who entered had to have faith in God's promises to perform that work. I can't imagine someone would show their lack of faith in God and His promises by having a rope tied around by ankle in case I died while I was in the Holy of Holies. The rope idea is probably more in the fanciful myth category instead of actual reality.
