In judging, do not let a man's position have any weight with you; give hearing equally to small and great; have no fear of any man, for it is God who is judge: and any cause in which you are not able to give a decision, you are to put before me and I will give it a hearing.

Or it may be said in the land from which you have taken them, Because the Lord was not able to take them into the land which he said he would give them, and because of his hate for them, he has taken them out to put them to death in the waste land.

And if the way is so long that you are not able to take these things to the place marked out by the Lord your God for his name, when he has given you his blessing, because it is far away from you;

Every man is to give as he is able, in the measure of the blessing which the Lord your God has given you.

If you are not able to give a decision as to who is responsible for a death, or who is right in a cause, or who gave the first blow in a fight, and there is a division of opinion about it in your town: then go to the place marked out by the Lord your God;

Then he said to them, I am now a hundred and twenty years old; I am no longer able to go out and come in: and the Lord has said to me, You are not to go over Jordan.
