New King James Version (NKJV)
Deuteronomy 18
17 And the Lord said to me: ’What they have spoken is good.
18 I will raise up for them a Prophet like you from among their brethren, and will put My words in His mouth, and He shall speak to them all that I command Him.
19 And it shall be that whoever will not hear My words, which He speaks in My name, I will require it of him.
20 But the prophet who presumes to speak a word in My name, which I have not commanded him to speak, or who speaks in the name of other gods, that prophet shall die.’
21 And if you say in your heart, ’How shall we know the word which the Lord has not spoken?’--
22 when a prophet speaks in the name of the Lord, if the thing does not happen or come to pass, that is the thing which the Lord has not spoken; the prophet has spoken it presumptuously; you shall not be afraid of him.
Deuteronomy 19
1 "When the Lord your God has cut off the nations whose land the Lord your God is giving you, and you dispossess them and dwell in their cities and in their houses,
2 you shall separate three cities for yourself in the midst of your land which the Lord your God is giving you to possess.
3 You shall prepare roads for yourself, and divide into three parts the territory of your land which the Lord your God is giving you to inherit, that any manslayer may flee there.
4 "And this is the case of the manslayer who flees there, that he may live: Whoever kills his neighbor unintentionally, not having hated him in time past--
5 as when a man goes to the woods with his neighbor to cut timber, and his hand swings a stroke with the ax to cut down the tree, and the head slips from the handle and strikes his neighbor so that he dies--he shall flee to one of these cities and live;
