וַתָּבֹ֖אוּ אֶל־הַמָּק֣וֹם הַזֶּ֑ה וַיֵּצֵ֣א סִיחֹ֣ן מֶֽלֶךְ־חֶ֠שְׁבּוֹן וְע֨וֹג מֶֽלֶךְ־הַבָּשָׁ֧ן לִקְרָאתֵ֛נוּ לַמִּלְחָמָ֖ה וַנַּכֵּֽם׃
Y llegasteis á este lugar, y salió Sehón rey de Hesbón, y Og rey de Basán, delante de nosotros para pelear, y herímoslos;
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”.
