'Ho' in the Bible

Then went Boaz up to the gate, and sat him down there: and, behold, the kinsman of whom Boaz spake came by; unto whom he said, Ho, such a one! turn aside, sit down here. And he turned aside, and sat down.

Ho, every one that thirsteth, come ye to the waters, and he that hath no money; come ye, buy, and eat; yea, come, buy wine and milk without money and without price.

Ho, ho, come forth, and flee from the land of the north, saith the LORD: for I have spread you abroad as the four winds of the heaven, saith the LORD.
