'Keepeth' in the Bible

And he that overcometh, and he that keepeth my works unto the end, to him will I give authority over the nations:

(Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walked naked, and they see his shame.)

And behold, I come quickly. Blessed is he that keepeth the words of the prophecy of this book.
