Do not let anyone who delights in false humility and the worship of angels disqualify you. Such people also go into great detail about what they have seen, and their unspiritual minds puff them up with idle notions.
NIV
Let no one defraud you by acting as an umpire and declaring you unworthy and disqualifying you for the prize, insisting on self-abasement and worship of angels, taking his stand on visions [he claims] he has seen, vainly puffed up by his sensuous notions and inflated by his unspiritual thoughts and fleshly conceit
AMP
Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,
KJV
Now, brothers and sisters, I have applied these things to myself and Apollos for your benefit, so that you may learn from us the meaning of the saying, "Do not go beyond what is written." Then you will not be puffed up in being a follower of one of us over against the other.
NIV
Now I have applied all this [about parties and factions] to myself and Apollos for your sakes, brethren, so that from what I have said of us [as illustrations], you may learn [to think of men in accordance with Scripture and] not to go beyond that which is written, that none of you may be puffed up and inflated with pride and boast in favor of one [minister and teacher] against another.
AMP
And these things, brethren, I have in a figure transferred to myself and to Apollos for your sakes; that ye might learn in us not to think of men above that which is written, that no one of you be puffed up for one against another.
KJV
