'Price' in the Bible

I have raised him up in righteousness, and I will make straight all his ways: he shall build my city, and he shall let my exiles go free, not for price nor reward, saith Jehovah of hosts.

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.
