Gen 18:30

וַ֠יֹּאמֶר אַל־נָ֞א יִ֤חַר לַֽאדֹנָי֙ וַאֲדַבֵּ֔רָה אוּלַ֛י יִמָּצְא֥וּן שָׁ֖ם שְׁלֹשִׁ֑ים וַיֹּ֨אמֶר֙ לֹ֣א אֶֽעֱשֶׂ֔ה אִם־אֶמְצָ֥א שָׁ֖ם שְׁלֹשִֽׁים׃

Then Abraham said, “May the Lord not be angry, but let me speak further. Suppose thirty are found there?” He replied, “If I find thirty there, I will not do it.”
