And Sehon the king of Hesebon would not let us pass: because the Lord thy God had hardened his spirit, and fixed his heart, that he might be delivered into thy hands, as now thou seest.
וְלֹ֣א אָבָ֗ה סִיחֹן֙ מֶ֣לֶךְ חֶשְׁבּ֔וֹן הַעֲבִרֵ֖נוּ בּ֑וֹ כִּֽי־הִקְשָׁה֩ יְהוָ֨ה אֱלֹהֶ֜יךָ אֶת־רוּח֗וֹ וְאִמֵּץ֙ אֶת־לְבָב֔וֹ לְמַ֛עַן תִּתּ֥וֹ בְיָדְךָ֖ כַּיּ֥וֹם הַזֶּֽה׃
One Church Father comments on this verse
It can be stated that the Lord made Zion's heart unyielding, much like He did with Pharaoh: His actions were just, for Zion committed wickedness just as Pharaoh did; thus, Zion faced destruction akin to Pharaoh's fate. Similarly, Og met his end in the same manner, as he mirrored Zion in every respect.
