2 yea, Jehovah saith unto Moses, `Speak unto Aaron thy brother, and he cometh not in at all times unto the sanctuary within the vail, unto the front of the mercy-seat, which [is] upon the ark, and he dieth not, for in a cloud I am seen upon the mercy-seat.
2
The LORD said to Moses: “Tell your brother Aaron that he is not to come whenever he chooses into the Most Holy Place behind the curtain in front of the atonement cover on the ark, or else he will die. For I will appear in the cloud over the atonement cover.
