Deut 1:28

אָנָ֣ה אֲנַ֣חְנוּ עֹלִ֗ים אַחֵינוּ֩ הֵמַ֨סּוּ אֶת־לְבָבֵ֜נוּ לֵאמֹ֗ר עַ֣ם גָּד֤וֹל וָרָם֙ מִמֶּ֔נּוּ עָרִ֛ים גְּדֹלֹ֥ת וּבְצוּרֹ֖ת בַּשָּׁמָ֑יִם וְגַם־בְּנֵ֥י עֲנָקִ֖ים רָאִ֥ינוּ שָֽׁם׃

Where can we go? Our brothers have made our hearts melt, saying: ‘The people are larger and taller than we are; the cities are large, with walls up to the heavens. We even saw the descendants of the Anakim there.’”
