וַתָּבֹ֖אוּ אֶל־הַמָּק֣וֹם הַזֶּ֑ה וַיֵּצֵ֣א סִיחֹ֣ן מֶֽלֶךְ־חֶ֠שְׁבּוֹן וְע֨וֹג מֶֽלֶךְ־הַבָּשָׁ֧ן לִקְרָאתֵ֛נוּ לַמִּלְחָמָ֖ה וַנַּכֵּֽם׃
너희로 떡도 먹지 못하며 포도주나 독주를 마시지 못하게 하셨음은 주는 너희 하나님 여호와이신 줄을 알게 하려 하심이니라
Ibn Ezra
You have seen, as well as the subsequent verse “I led you…” [: 4] and the subsequent mention of how ‘Og came out to wage war [: 6] are to be understood in the sense of, “There are among you those who have witnessed the signs which God performed in Egypt; both they and the next generation have witnessed the wonder of eating no bread other than the manna; and the younger generation witnessed how God aided them in the defeat of the two kings”.
