All of this verse is wanting in the oldest and best
manuscripts like Aleph B C D W 33 Old Syriac, Coptic versions,
Latin Vulgate. It is undoubtedly added, like the clause in verse
 3 , to make clearer the statement in verse  7 . Tertullian is
the earliest writer to mention it. The Jews explained the healing
virtues of the intermittent spring by the ministry of angels. But
the periodicity of such angelic visits makes it difficult to
believe. It is a relief to many to know that the verse is
spurious.
