And thou shalt make them linen breeches to cover the flesh of their nakedness; from the loins even unto the thighs they shall reach: (ASV)
After describing what priests are to wear in lovingly minute detail, we find that they ought to wear special underwear in holy places, so they don't expose themselves to such places, a concern also expressed in Exodus 20:26.
Again, nothing really errant about this. There are parts of the bible that seem ridiculous, (like how you can eat fish but not shellfish), but that has nothing to do with errancy.
