One very obscure part of Torah is the part that shows the actual Moses's writings. I am talking about Moses's letters of'course.
Let's take a look:
YLT Num 20:14 . And Moses sendeth messengers from Kadesh unto the king of Edom, 'Thus said thy brother Israel, Thou--thou hast known all the travail which hath found us;
YLT Num 20:15 that our fathers go down to Egypt, and we dwell in Egypt many days, and the Egyptians do evil to us and to our fathers;
YLT Num 20:16 and we cry unto Jehovah, and He heareth our voice, and sendeth a messenger, and is bringing us out of Egypt; and lo, we are in Kadesh, a city in the extremity of thy border.
YLT Num 20:17 Let us pass over, we pray thee, through thy land; we pass not over through a field, or through a vineyard, nor do we drink waters of a well; the way of the king we go, we turn not aside--right or left--till that we pass over thy border.'
YLT Num 20:18 And Edom saith unto him, 'Thou dost not pass over through me, lest with sword I come out to meet thee.'
YLT Num 20:19 And the sons of Israel say unto him, 'In the highway we go, and if of thy waters we drink--I and my cattle--then I have given their price; only (it is nothing) on my feet I pass over.'
YLT Num 20:20 And he saith, 'Thou dost not pass over;' and Edom cometh out to meet him with much people, and with a strong hand;
YLT Num 20:21 and Edom refuseth to suffer Israel to pass over through his border, and Israel turneth aside from off him.
YLT Dt 2:26 'And I send messengers from the wilderness of Kedemoth, unto Sihon king of Heshbon,--words of peace--saying,
YLT Dt 2:27 Let me pass over through thy land; in the several ways I go; I turn not aside--right or left--
YLT Dt 2:28 food for money thou dost sell me, and I have eaten; and water for money thou dost give to me, and I have drunk; only, let me pass over on my feet,--
YLT Dt 2:29 as the sons of Esau who are dwelling in Seir, and the Moabites who are dwelling in Ar, have done to me--till that I pass over the Jordan, unto the land which Jehovah our God is giving to us.
YLT Dt 2:30 'And Sihon king of Heshbon hath not been willing to let us pass over by him, for Jehovah thy God hath hardened his spirit, and strengthened his heart, so as to give him into thy hand as at this day.
YLT Dt 2:31 'And Jehovah saith unto me, See, I have begun to give before thee Sihon and his land; begin to possess--to possess his land.
YLT Dt 2:32 'And Sihon cometh out to meet us, he and all his people, to battle to Jahaz;
YLT Dt 2:33 and Jehovah our God giveth him before us, and we smite him, and his sons, and all his people;
YLT Dt 2:34 and we capture all his cities at that time, and devote the whole city, men, and the women, and the infants--we have not left a remnant;
YLT Dt 2:35 only, the cattle we have spoiled for ourselves, and the spoil of the cities which we have captured.As you can see from these two letters, Moses shows absolute humility even to his enemies in order to preserve life. Moses has God on his side but he still chooses diplomacy over war. In fact, as the first letter shows, Moses has to yield to his brother Edom.
These two letters appear to be similar in style so they are undoubtedly represent the original Moses's writings. It is not a lot to judge about Moses's character, but they do provide some basic details like the those mentioned above.
