וְאִם־בְּרִיאָ֞ה יִבְרָ֣א יְהוָ֗ה וּפָצְתָ֨ה הָאֲדָמָ֤ה אֶת־פִּ֙יהָ֙ וּבָלְעָ֤ה אֹתָם֙ וְאֶת־כָּל־אֲשֶׁ֣ר לָהֶ֔ם וְיָרְד֥וּ חַיִּ֖ים שְׁאֹ֑לָה וִֽידַעְתֶּ֕ם כִּ֧י נִֽאֲצ֛וּ הָאֲנָשִׁ֥ים הָאֵ֖לֶּה אֶת־יְהוָֽה׃
But if the LORD make a new thing, and the ground open her mouth, and swallow them up, with all that appertain unto them, and they go down alive into the pit, then ye shall understand that these men have despised the LORD.’
