NET

23 Even though they have the appearance of wisdom with their self-imposed worship and humility achieved by an unsparing treatment of the body—a wisdom with no true value—they in reality result in fleshly indulgence.

Darby

23 (which have indeed an appearance^D8760 of wisdom in voluntary worship, and humility, and harsh treatment of the body, not in a certain honour,) to [the] satisfaction of the flesh^D8761.

Darby Bible Notes

appearance - Logos. there was something to allege, to say for it. flesh - The clause in parentheses is to show that the harsh usage of the body, and all the teaching of the seducer, was for (or 'as to') the satisfaction of the flesh; 'a certain honour' is what is due to the body.

KJV

23 Which things have indeed a shew of wisdom in will worship, and humility, and neglecting^K7074of the body; not in any honour to the satisfying of the flesh.

KJV Bible Notes
