18 let no one beguile you of your prize, delighting in humble-mindedness and [in] worship of the messengers, intruding into the things he hath not seen, being vainly puffed up by the mind of his flesh,
18
Do not let anyone who delights in false humility and the worship of angels disqualify you. Such a person also goes into great detail about what they have seen; they are puffed up with idle notions by their unspiritual mind.
