King James Version
But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.English Standard Version
But these people blaspheme all that they do not understand, and they are destroyed by all that they, like unreasoning animals, understand instinctively.New International Version
Yet these men speak abusively against whatever they do not understand; and what things they do understand by instinct, like unreasoning animals--these are the very things that destroy them.
