Jude 1:10

10 Yet these people slander whatever they do not understand, and the very things they do understand by instinct—as irrational animals do—will destroy them.

Read Jude 1:10 Using Other Translations

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.
But these people blaspheme all that they do not understand, and they are destroyed by all that they, like unreasoning animals, understand instinctively.
But these people scoff at things they do not understand. Like unthinking animals, they do whatever their instincts tell them, and so they bring about their own destruction.
