'Doeth' in the Bible

Every one that cometh unto me, and heareth my words, and doeth them, I will show you to whom he is like:

But he that heareth, and doeth not, is like a man that built a house upon the earth without a foundation; against which the stream brake, and straightway it fell in; and the ruin of that house was great.

For I also am a man set under authority, having under myself soldiers: and I say to this one, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it.
