Devarim 2:29-31

Orthodox Jewish Bible

²⁹ (As the Bnei Esav which dwell in Seir, and the Moavim which dwell in Ar, did unto me;) until I shall pass over Yarden into the land which Hashem Eloheinu giveth us.

³⁰ But Sichon Melech Cheshbon would not let us pass by him; for Hashem Eloheicha hardened and made stubborn his ruach, and made his lev obstinate, that He might deliver him into thy hand, as indeed hayom hazeh.

³¹ And Hashem said unto me, See, I have begun to give Sichon and his land before thee; begin the occupation, that thou mayest take possession to inherit his land.
